Plan | Player Analytics

Plan | Player Analytics 5.6 build 2614

5.5 build 2100 - 6 years of Plan!
This release contains a lot of things. Frontend BETA enters next phase since all pages have been rewritten in React, next steps are export and html customization implementation for it. This update also contains data gathering fixes, additions, new placeholders along with other bugfixes.
Today also marks 6th year of Plan development! As is customary at this point there's a Year in Review -post after the change log.
Special thanks to Vankka, angela0930 for contributions to this update
Change log
Data Gathering
  • Removed data after null-byte in Join Address data. Bungeecord and Velocity use the handshake-packet to forward UUID and IP information of players, and since the join address comes from handshake packet, that data ended up in the join addresses Plan gathered. Forge Mod Loader forwards its version information in the same handshake packet in similar fashion. Discarding data after the null-byte should resolve any issues.
Frontend BETA
  • Names of new players are now shown in Light Green in PvP tables when they are the player who was killed within 24h of their first join. This is to help find players who kill newer players.
  • /query page has been rewritten in React.
  • /register page has been rewritten in React
  • Fixed plugin cards overlapping when moving to different page on a table
  • Fixed /network/... redirecting to /network
  • Fixed colors of buttons when hovering mouse on them
I'm excited, the frontend part of rewrite is complete and I can move to implementing export and html customization for the new frontend.
  • Experimental version of export for React version is now enabled if Frontend BETA and Export are both enabled. This will place index.html at the root of the export directory along with all the react files. I have not yet been able to test it properly, so it might be completely unusable. Just throwing it out there.
DataExtension API: Component API by Vankka
If your plugin's data contains chat colors or mini-message information, that information can now be included so that it will eventually show up on the website. Check documentation for the new API here
  • Vankka fixed error that occurred when deleting LuckPerms groups
  • Vankka fixed LuckPerms not showing colors properly on the website
Added new placeholders
  • %plan_time_active_{day/week/month}%
  • %plan_time_active_{day/week/month}_raw%
  • %plan_top_player_kills_{day/week/month/total}_{n}%
  • angela0930 updated ZH_TW locale
  • Fixed ConcurrentModificationException related to world aliases
  • Fixed some queries erroring in Strict group by mode for MySQL
  • Fixed Ore not showing Plan sponge version
  • Fixed removal of cookies that expired while server was offline
  • Fixed RemoveUsernameFromAccessLogPatch applying every time
  • Changed "Database can't keep up with transactions" to less dire message
  • Fixed SQLITE_CONSTRAINT_NOTNULL when request uri is null
Year in review: Year 6
This year has been a lot different from the previous five, since there has been a lot more things going on in my personal life. Last year I got a job, and in January I started writing my Master’s thesis. It was very tough balancing all that on top of developing Plan on the side. I had to take some months off development entirely with a hiatus in the summer and fall to finish up the thesis. In September I returned the thesis for review and I’m happy to now have graduated! Things definitely calmed down after finishing up the thesis and resuming Plan development after the hiatus.

The running theme this year has been steady and stable changes. Inspired by the answers to last year’s poll, the goals for this year were to improve the loading speed of the website, as well as visualizing more of the gathered data.

There’s been a lot of work done this year towards those goals. The database schema was changed drastically, the webserver was changed to Jetty, and Frontend BETA is rewriting the code running in browser to React. Alone each change brings small improvements, but together they improve things a lot.
I’m very excited for the future, since the React frontend speeds up development of new things considerably thanks to environment where changes can be seen instantly. Previously I would have had to compile Plan and restart the test server – It takes 1 second vs 3 minutes it used to take to see changes now.

Main goals for 2023 is to get the new frontend out of Beta after feature parity with previous frontend is reached (Export and Html Customization still to go), and after that it’ll be time to tackle a lot of tickets with ’Visualization’ tag. A lot of the ongoing work has been done to make the future changes easier to do, which should speed up feature additions in the upcoming year.

I’m very happy that all the automation created in the past years is now finally paying off, helping keep confidence in that everything works as intended when changing something. I love that it’s now possible to deliver development builds fast, even within the same hour when someone is asking for help.

Special thanks to Github sponsors, donators, discord moderators, support, and contributors this year! Extra special thanks to Kopo & Vankka for their constant input into the project.

5.5 build 1951 - Change log
This release contains update to Java 11, Sponge 8, Fabric 1.19.1, as well as Webserver rewrite to Jetty. In addition it contains new features and improvements, and more progress on Frontent BETA in the form of rewritten server & network pages.

Special thanks to Vankka, Kopo, Drex & stashenko for contributions to this update

Change Log
Breaking changes
This version updates config so backup your config in case you need to revert back to 5.4!
  • Java 11: Plan now requires Java 11 or newer to run. Java 8 is no longer supported.
  • Sponge API 8: Sponge API 7 is no longer supported.
  • Fabric 1.19.1: Fabric 1.18 is no longer supported
If you can't update, you can continue using 5.4 build 1722 even if connected to same database as newer versions. (No database schema changes!)

Supported APIs
  • Updated to Java 11, which was required by Jetty and Sponge API 8.
  • Vankka implemented Sponge API 8 changes.
  • Drex implemented support for Fabric 1.19.1
New features
Jetty Webserver

New webserver implementation speeds up response transmission times considerably
  • Replaced Sun Webserver with Jetty (, an open source embedded webserver library.
  • Plan now supports HTTP/2
  • Plan now supports TLSv1.3 for HTTPS, and browsers have a larger selection of cipher suites they can use.
    • Users of PlanCert.jks (Included in the jar) are encouraged to create their own self signed cert. I had to implement some extra code to support expired certificate (Since PlanCert.jks inside the jar has expired), and that may not be as secure as creating a new self-signed .p12 - Instructions will be added to the wiki, but the plugin also logs the instructions if you use that cert.
  • Fixed gzip compression for responses (speeds up transmission)
Access log
Access logs are now stored in Plan database in plan_access_log table.
  • You can also log access to console with Webserver.Security.Access_log.Print_to_console (default false) in the config. This is useful for debugging reverse-proxy issues.
  • The IP of each request is stored in the database - as it is necessary for security (a valid legal basis for use with GDPR).
  • The request logs in database are removed after Webserver.Security.Access_log.Remove_logs_after_days (default 30)
Plan json endpoints are now documented with Swagger available on the webserver itself. You can access the Swagger documentation from /docs on your Plan webserver after updating.

Data Gathering
  • Fabric should now gather join addresses correctly. Previously player IPs were gathered by mistake. To clear the invalid data use /plan db removejoinaddresses {servername} once you install the plugin.
  • Added 'Data_gathering.Preserve_join_address_case' setting (default false) that attempts to preserve join address case. Note that some servers/clients may lowercase addresses regardless.
  • Possibly fixed an issue where Quit event is processed before Join, leading to long incorrect sessions being stored on next join/shutdown
  • Possibly fixed an issue where saving sessions that ended on shutdown failed when another join had just stored one of the join addresses that were previously unseen. (It would retry next reload and probably succeed - so low priority issue.)
Frontend BETA progress
Enable with Plugin.Frontend_BETA setting in the config. Note that Html Customization and Export are not yet supported in the beta.
  • Rewrote /login page in React
  • Rewrote /server page in React
    • You can now switch between visualizations for 'current playerbase' and 'latest join address' pie-graphs
    • Join addresses by day graph is now available to analyze incoming join addresses further.
  • Rewrote /network page in React
    • You can now switch between Map projections in Geolocations
    • You can now sort servers in server list by specific values
    • Join addresses by day graph also available for network page
    • Added Players online to network performance tab - data from multiple servers can be viewed in one graph on network performance tab
  • Fixed various issues and cleaned up overall appearance
You can track progress of frontend beta here

  • Fixed lag caused by large tab completion results if server had a lot of players and someone tab completed /plan player .
  • Fixed empty cookies preventing Plan login due to error
  • Reduced maximum join address length to 191 characters due to limitation of old MySQL versions
  • Added plan.command permission (default: true) on Spigot servers to allow hiding /plan command from tab completion by negating this permission
  • Config structure was modified to be valid yaml so that other programs can validate it. The config is updated automatically with current values of old config versions.
  • Increased default inactive player removal threshold 180 days -> 3650 days (10 years). This change is not applied automatically to old configs.
  • stashenko updated RU locale
  • Added /plan db migrate_to_online_uuids command to help migrating from an offline-mode server to online-mode
    • Moves data of offline uuids to online uuids (Looks up online uuid from Mojang)
    • Combines data of offline uuids and online uuids if both exist
    • See /plan db for more help
  • Plugin method calls should no longer be made during Plan disable.
  • Updated PlotSquared extension, should now register correctly
  • Updated Floodgate extension, should now register correctly
  • Updated Nucleus extension for Sponge 8
  • Removed RedProtect support for Sponge (No longer supported in Sponge 8)
  • Dev builds for every commit is now available DEV build pipeline (Click on title and scroll down to Artifacts, note that you need to log in to Github.)
Change log 5.4 build 1722
This update fixes fabric 1.19 support and join address gathering.
Special thanks to Kopo for contributions to this update.
Change log
Fix join address gathering (No longer 'Unknown')
An oversight in the way the player leave listener code was structured caused the player join address to be removed from memory before its linking to the session that was ending.
It is now fixed.
Fabric 1.19 support
Kopo fixed fabric pipeline for 1.19 - Unfortunately the changes are incompatible with older versions of fabric. If you need older version of fabric use older version of Plan.
Frontend BETA
  • /players page rewritten in React now available when opted in to frontend beta
    • Note that no fixes to functionality were added to it yet, just implementation in React.
  • Server page rewrite is making good progress and is about 75% complete.
Server identification
  • Possibly fixed ServerInfoFile.yml clearing and server duplicating if MySQL is busy during enable
5.4 build 1690
This update fixes some annoying bugs and prepares the plugin for the move to 5.5 and Java 11 while keeping this version compatible for those unable to update their servers to Java 11.
If no further critical bugs surface next update will be 5.5.
Change log
Plugin stability
  • Fixed issue where Plan would prevent server enable from continuing if database was not responsive during enable.
  • Fixed 2 crashes when database write latency is high
    • Fixed thread starvation crash during high latency when using ViaVersion or ProtocolSupport
    • Reduced chance of out of memory crash when during high latency by starting to drop plugin data transactions for a while if queue grows over 500 transactions. (The transactions continue if queue returns to <50)
Join address schema change
  • Join addresses are now stored in plan_join_address table and id referencing that is added to plan_sessions table for time based analysis implementation later.
    • Backwards compatible schema change - old versions will insert 'unknown' as each sessions address.
    • plan_user_info.join_address column was not removed, but its use is discouraged for 3rd parties as its use may be removed in the future.
Fixes to patches
  • Fixed UserInfoOptimizationPatch resetting join_address data when applied
  • Fixed typo in RemoveDanglingServerDataPatch that caused it to fail
  • Possibly improved speed of RemoveDanglingUserDataPatch
Other fixes to database
  • Prevented transactions from executing if database ran into fatal error. This reduces amount of errors logged on a failed patch
  • Fixed error related to user_id constraint violation for Ping and Session store transactions. If they execute faster than the user register transaction the player will not have up-to-date information until the proper transaction executes, but the storage of other data will no longer fail.
  • Prevented ActiveCookieStore related DbOpException if plugin failed to enable
  • Server page > Performance now lists Average players under Performance as Numbers.
Frontend BETA
  • Implemented player ping graph on the player page when opted into frontend beta
  • Fixed nickname list not showing colors properly
  • Fixed terminal icon not loading when user registered with console
  • Fallback to using relative address if Alternative_IP is misconfigured to reduce confusion. Previously nothing would load if address was different, now there's a chance something loads.
  • Wrote tests for placeholders
    • Fixed player_recent_kill_{1-10} and player_recent_death_{1-10} off-by-one mistake and related error for n=10.
    • Fixed player_unique_players_today erroring if there had been no sessions during today.
  • New placeholders
    • %plan_player_current_session_length%: The length of active session (Online time)
    • %plan_player_current_session_length_raw%: unformatted ms
    • %plan_player_latest_session_length%: The length of active session or previous session if not online
    • %plan_player_latest_session_length_raw%: unformatted ms
    • %plan_player_previous_session_length%: The length of previous non-active session even if online
    • %plan_player_previous_session_length_raw%: unformatted ms
  • player_ placeholders now support adding :playername or :uuid at the end of placeholder to show data for another player
    • Note that if the player by given identifier is not found the placeholder is not replaced.
Other bugfixes
  • Console will now log colors properly on Bukkit and Bungee based servers
  • Fixed some _raw placeholders from being formatted
  • Fixed Error related to GriefDefender Extension
Bugfixes - Change log 5.4 build 1633

This update brings a couple important bugfixes to build 1628. Please read change log of 1628 if you're running older build than 1628.

Change log
  • Fixed databases failing to patch schema if plan_users or plan_servers were missing rows that had uuids in other tables.
    This affected roughly ~1 in 80 servers based on reports and metrics.
    This problem could occur if server had shutdown at a specific time during player join, or if someone had deleted rows manually from plan_users or plan_servers.
    • The fix deletes dangling data so that the rest of the patches can execute properly.
    • If you have run into this problem on your server this update should fix your database automatically.
  • Fixed SQL errors in ViaVersion Extension and ProtocolSupport Extension
Frontend BETA and Database optimizations - Change log 5.4 build 1628

Hello! This update brings some great database optimizations, beginning of Frontend BETA (Opt-in), as well as small fixes. Read more below

⚠ This update is backwards incompatible due to database schema changes.
Servers with old Plan versions should not be enabled after starting a server with this update installed.

How to prepare for this update

Networks: Make sure to update all servers that are connected to the database!
If an old version starts with the new database schema it will attempt to reverse some of the new changes.
Special thanks to Kopo, Pingger & KasperiP for contributions to this update.

Change log
Database optimizations (Schema changes)
A lot of work was put into analyzing bottlenecks in queries and slow query logs sent in by users.

Benchmarks using 17k players are promising, as /players page now loads in 5s vs 2+min before.

Database patches will apply on first enable of the update to modify the database schema. This can take up to 4 minutes. Networks: Only enable one Plan server and wait for it to patch database before starting other servers.

Changed database schema to optimize query speed and table size
If you're using these columns via Query API you can replace your use case:
If you need uuid in ResultSet, use SELECT u.uuid ... JOIN plan_users u on<table>.user_id
If you have uuid or server uuid in WHERE, use server_id=(SELECT id FROM plan_servers WHERE uuid='<server uuid>')
Some queries that were identified as slow were optimized to perform better by changing the query
Geolocations queries
Ping country table query
Player table query
Other queries are also sped up by the uuid -> user_id and server_uuid -> server_id changes, as comparing integers is faster than Strings.
Extension data insert was made faster by keeping icon ids in memory for short duration
MySQL insert performance may be improved since auto-commit was turned off
Query page queries now use user ids instead of uuids - this fixes 'Max SQL size exceeded' issues.
Added a new index to plan_ping table to speed up ping queries.
Removed redundant uuid indexes that are now replaced with foreign key indexes for user_id and server_id, which reduces database size.
Frontend BETA (Opt-in)
Frontend is being rewritten in React one page at a time. This is to have more control over what is displayed on the website, since a lot of requested features will require more interaction or hiding features partially. - While doable with vanilla javascript, code would quickly become unmaintainable.

The goal is to get feature parity with the current frontend implementation by rewriting one page at a time and then switch over completely.

Some features will not use React frontend until everything is complete.

To Opt-in set Plugin.Frontend_BETA to true
Player page has been rewritten in React, other pages still use previous implementation.
Html Customization is currently incompatible with the beta and is disabled automatically.
Export is currently incompatible with the beta and old pages continue to be exported even if beta is enabled.
Automated browser testing was improved a lot and all pages are now tested for basic javascript errors.
Data gathering
Fixed AFK time not being gathered on Fabric, the movement detector was incorrectly firing every time a player position packet arrived (Happens once per second).
Default Player head image address was changed from cravatar to crafatar. Remove the whole row from the config and reload Plan if you wish to use the new setting.
Kopo did a massive locale system improvement in order to support translations on the frontend side, implementing yml conversion, namespacing all of the existing locale keys and writing json endpoints for frontend to load locale - as well as the code responsible for loading those using i18next.

Locale files now use .yml format. Any locale files you may be using are converted automatically.
The new React Frontend allows changing language on the frontend on a per-user basis with a dropdown menu - This is currently only available on the rewritten pages (player page)
KasperiP fixed a typo in Finnish locale
Players page is now exported more frequently
Exported pages should no longer show the Logout button
Essentials Economy was split from Essentials Extension. Now there are 2 extensions managed separately. This was done since the economy calls were triggering updates too frequently. If you have disabled Essentials Extension you may need to disable EssentialsEco Extension separately
Fixed NPE related to LuckPerms Extension
Fixed SQL syntax error related to LuckPerms Extension
Fixed issues with KingdomsX Extension when using newer version of KingdomsX (They changed names of some of their packages)
Pingger added support for 1.18 stone blocks to LogBlock Extension
QoL changes
/plan servers command now lists Plan version on each server so it is easier to keep track of servers being out of date.
Fixed negative register dates in player dat files breaking the database
Fixed ConcurrentModificationException related to AFK tracker
Prevented use of incorrectly formatted WorldAlias regex settings
Fixed Plan failing to enable if database query took too long during enable.
5.4 build 1583 - Hotfix for MySQL issue
This release contains a hotfix for MySQL driver unloading issues on disable/reload, causing the plugin to spew a really long error message and failing to reload when using MySQL.
Driver is no longer unloaded during reload to avoid any issues.
This bug was introduced in dev build 1536 on January 6th, but it was not caught or reported.
