VMware monitoring
MAGIC● Point Zabbix at VMware API● It discovers vSpheres● It discovers virtual machines● (and monitors them)
Various improvements
● Web monitoring● Length limits increased● Improved filters in the frontend● Validation
More caching
● Never (almost) check last value only– avg(5m)
– ...and hammer the database
● “value cache” to the rescue
2.4
Ad-hoc graphing
Flexible agent filtering
● Discover:– network interfaces
– file systems● by type● by mountpoint
– CPUs
– ...extend
...by the way, Zabbix agent
● Native on many platforms● More than 70 different things built-in
Web monitoring
● Custom headers● SSL auth
Standards, baby
ISO 8601
My favourite 2.4 feature
● Changing loglevel runtime● ...for individual processes● ...and also ability to dump web scenario details● ...and the same for VMware monitoring
Upgrade policies
● No database changes in one major release● All old agents supported
SERIOUS BUG
