Agent and modules generated by the plugin

The plugin will create one agent for every HAProxy URL configured. The agent name is computed as an ~~agent,~~MD5 ~~each~~hash ~~instance with~~of the ~~name~~URL ~~taken from the URL. If it's in advanced mode, it will create the number of agents depending on the blocks sent,~~netloc, and the ~~name~~alias ~~will~~is beset ~~defined~~to bythat ~~the~~same netloc (for example, 192.168.0.10:8404). Each agent ~~name field. Otherwise, it will also take the name from the URL if no name is specified. It will contain~~includes the modules obtained by ~~interacting~~parsing ~~with~~the HAProxy CSV stats endpoint.

The status module is created always for every row, regardless of the monitor tokens, in order to alert on DOWN/MAINT/STOP states. The remaining numeric fields are included as generic_data (integer/decimal) or generic_data_string (string) modules, following the format <pxname>_<svname>_<field>.

The main fields available in the HAProxy CSV that generate modules are:

The status module is calculatedtranslated asto a ratenumeric ofvalue change for the Total requests statistics., Total kBytes:The total kilobytes of data served by the Apache server since its last start/restart., Total Duration:The cumulative time spent processing all requests since the server started (in microseconds or milliseconds, depending on Apache version and configuration). This can be higher than Uptime because multiple processes/threads can be active simultaneously., CPUUser:The CPU time used by Apache processes in user mode since the server started, expressed as a percentage., CPUSystem:The CPU time used by Apache processes in system (kernel) mode since the server started, expressed as a percentage., CPUChildrenUser:The CPU time used by child processes of Apache in user mode., CPUChildrenSystem:The CPU time used by child processes of Apache in system (kernel) mode., CPULoad:The overall CPU load percentage consumed by all Apache processes combined since the server started., Uptime:The human-readable representation of the server's uptime (e.g., '2 days 4 hours 40 minutes'). This is derived from ServerUptimeSeconds., ReqPerSec:The average number of requests served per second since the server was started/restarted. ReqPerSec is not used, as it counts the average since the last Apache server start., BytesPerSec:The average number of bytes served per second since the server was started/restarted. BytesPerSec is not used, as it counts the average since the last Apache server start., BytesPerReq:The average number of bytes served per request since the server was started/restarted. The average number of client requests per second., # Note: The Zabbix description for BytesPerReq seems to confuse it with ReqPerSec. BytesPerReq is bytes per request. DurationPerReq:The average duration (time) it took to serve each request since the server was started/restarted (in milliseconds or microseconds)., BusyWorkers:The total number of worker threads/processes that are currently busy handling requests., GracefulWorkers:The number of worker processes that are currently in a graceful shutdown state (waiting for current requests to finish before exiting)., IdleWorkers:The total number of worker threads/processes that are currently idle and ready to handle new requests., Processes:The number of active Apache processes (not threads) currently running., Stopping:The number of worker processes that are in a stopping state., ConnsTotal:The total number of connectionsaccording to the Apachefollowing server.,mapping: ConnsAsyncWriting:The5=UP, number4=OPEN, of3=NOLB, asynchronous2=MAINT, connections1=STOP/STOPPING, in0=DOWN, writingwhich stateallows configuring alerts based on warning (applicable2-4) onlyand to the event MPM)., ConnsAsyncKeepAlive:The number of asynchronous connections in keep-alive statecritical (applicable0-2) only to the event MPM)., ConnsAsyncClosing:The number of asynchronous connections in closing state (applicable only to the event MPM)., CacheType:The type of cache mechanism being used by Apache (e.g., SHMCB for shared memory caching)., CacheSharedMemory:The total amount of shared memory allocated for the cache (in bytes or kilobytes)., CacheCurrentEntries:The current number of entries stored in the cache., CacheSubcaches:The number of subcaches within the main cache (for internal organization)., CacheIndexesPerSubcaches:The number of index entries per subcache., CacheIndexUsage:The percentage of the cache index space currently in use., CacheUsage:The overall percentage of the cache memory currently in use., CacheStoreCount:The total number of times an item has been successfully stored in the cache., CacheReplaceCount:The total number of times an existing cache entry has been replaced., CacheExpireCount:The total number of times a cache entry has expired., CacheDiscardCount:The total number of times a cache entry has been discarded (e.g., due to space limits or errors)., CacheRetrieveHitCount:The total number of times a requested item was found in the cache (cache hit)., CacheRetrieveMissCount:The total number of times a requested item was not found in the cache (cache miss)., CacheRemoveHitCount:The total number of times an item was successfully removed from the cache when it was found., CacheRemoveMissCount:The total number of times an item was attempted to be removed from the cache but was not found.
