What does each level ('Level 3', 'Level 2', 'Level 1') in production_snmp_stats_runner.log mean?
In recent versions of OnApp we use SNMP to gather stats from VMs like HV and VM uptime stats, resource usage stats, as well as disk information. The SNMP logs are held in /onapp/interface/log/production_snmp_stats_runner.log.
There are three levels of an SNMP statistics gathering:
Level 1 - every 10 seconds. CP gets info about hypervisors uptime/virtual servers' statuses. Level 2 - every 60 seconds. CP gets info about the disk usage, network usage, CPU usage statistics and the list of virtual servers. Level 3 - every 120 seconds. CP gets list of volume groups and logical volumes.
The level values can be changed in the onapp.yml file. For details, see Advanced Configuration Settings section.
