Hi all,

This is my first post, and I'm a not so newbie user of Observium. If my question has been answered, or if its now correct, please advise. We're using Observium latest community edition as below: [cid:image001.png@01D4EFC3.4368A660] Situation: where monitoring a lot of virtual servers in a VMware environment, and we use docker in a lot of those vm's. What's happens is, as usual in docker, a lot of network devices are created, and observium correctly detects those ports. However in a small period of time they're gone, however Observium keep track of them, and keep the RRD files. In a specific case, we've got : [cid:image002.png@01D4EFC3.4368A660]

Result... RRD for this server as... 200G!

Anyone has had this problem? I was thinking about using the config['bad_if'][] with something similar of veth*, but I think is not possible.

Any advice would be quite helpful!

Thanks,

Hi,

seems as you can use (add) config option:

$config['bad_if_regexp'][] = "/^veth[0-9a-f]+$/";

Hey all,

Mike, it worked like a charm :D Now the situation is much more manageable. Now I'm justing trying to cope with the old data. I'm doing a housekeeping -p, to see if it works.

Is there a way of cleaning this Caching DB?
