Implement detailed monitoring of container hosts
Monitoring so far has only be done from the outside, checking that websites and other services were available.
Now the need has risen to get monitoring of things like used disk space as well (some hosts almost run out of disk space). For that to be possible we need some kind of agent installed on the host. For Zabbix, we have 2 options:
- SNMP
- Zabbix agent
So we need to choose what method we are going to use. One consideration we need to take into account is security, especially for the builder hosts.
