Rihards Olups - Zabbix log management
0 likes•505 views
This document provides an overview of log management in Zabbix. It discusses configuring logging parameters like LogFile, LogFileSize, and DebugLevel in pre-3.0 and 3.0+ versions. It also describes the log format, potential log-related issues, different DebugLevel values and their associated levels of log detail, and the ability to change the log level at runtime introduced in Zabbix 2.4.

Rihards Olups - Zabbix log management
- 1. Zabbix Log Management Crash Course Running time: 50 minutes
- 2. Configuring logging Pre-3.0 ● LogFile (if not set, syslog used) ● LogFileSize ● DebugLevel
- 3. Configuring Logging in 3.0 3.0+ ● LogType – system/file/console ● LogFile (if LogType=file) ● LogFileSize ● DebugLevel
- 4. Log Format Not configurable 1714:20160909:031847.509 log message PID date time ms
- 5. Log-related Issues Each process opens logfile individually Holds two filedescriptors May keep deleted logfiles around (improved in 3.0) Zabbix processes may hang (ZBX-3788) http://blog.zabbix.com/mysterious-zabbix-problems-how-we-debug-them
- 6. DebugLevel 0 - basic information about starting and stopping of Zabbix processes 1 - critical information 2 - error information 3 - warnings 4 - for debugging (produces lots of information) 5 - extended debugging (produces even more information)
- 7. Which One Is Sane? Almost everybody runs at DebugLevel=3 Embedded devices – lower levels DebugLevel=4 – if there are known problems
- 8. The Less Sane Ones ● 4 - for debugging (produces lots of information) ● 5 - extended debugging (produces even more information) But what's "lots of information" and "even more information"?
- 9. DebugLevel 4 __zbx_zbx_setproctitle() title:'timer #1 [processed 1 triggers, 0 events in 0.006850 sec, 0 maintenances in 0.000000 sec, processing maintenance periods]' In process_maintenance() query [txnlev:0] [select m.maintenanceid,m.maintenance_type,m.active_since,tp.timeperiod _type,tp.every,tp.month,tp.dayofweek,tp.day,tp.start_time,tp.period,tp .start_date from maintenances m,maintenances_windows mw,timeperiods tp where m.maintenanceid=mw.maintenanceid and mw.timeperiodid=tp.timeperiodid and m.active_since<=1473415320 and m.active_till>1473415320] In update_maintenance_hosts()
- 10. DebugLevel 5 DebugLevel=5 adds: ● Received page in webmonitoring ● Received XML in VMware monitoring http://blog.zabbix.com/zabbix-2-4-features-part-8-debugging-web-and-vmware-monitoring
- 11. Runtime Loglevel Changing Awesome (not just great) In 2.4 – many upgraded http://blog.zabbix.com/zabbix-2-4-features-part-6-runtime-loglevel-changing
- 12. Change Loglevel for... Whole Zabbix One Zabbix process type Single Zabbix process (by pocess type & number) Single Zabbix process (by PID)
- 13. Examples zabbix_server --runtime-control log_level_increase zabbix_server -R log_level_increase=poller zabbix_server -R log_level_increase=trapper,3 zabbix_server -R log_level_increase=12345
