After Zabbix is installed and configured, a moment comes when maintenance tasks become important. In this last chapter we looked at three important tasks:
Tuning for performance
Reviewing Zabbix built-in auditing capabilities
Creating backups
The database performance bottleneck is the one most often reached, and as we found out, we could attack this problem from different angles. We could reduce the write load, distribute it, or increase database performance itself using both software level tuning and hardware improvements.
If you notice a sudden change in Zabbix server behavior like load increase, it can be very helpful to find out what configuration changes have been performed just prior to that. And if there are multiple Zabbix administrators, it is even better, as you can find out who exactly performed a specific change. This is where the built-in auditing capabilities of Zabbix help a lot by providing a change list and also exact change details for many operations.
And reaching one...
