[collectd] Configure reporting interval on network plugin

[Joel Serrano]

So, an update here:

Gathering CPU + 3 SNMP OIDs:

23:20:30.342653 IP 10.0.X.X.59192 > 10.0.Z.Z.25826: UDP, length 1308
23:21:20.341185 IP 10.0.X.X.59192 > 10.0.Z.Z.25826: UDP, length 1308
23:22:10.341337 IP 10.0.X.X.59192 > 10.0.Z.Z.25826: UDP, length 1308
23:23:00.341386 IP 10.0.X.X.59192 > 10.0.Z.Z.25826: UDP, length 1308

(50s approx)

Now, I added the memory. (CPU + 3 SNMP OIDs + MEMORY)

New results:

23:24:11.226821 IP 10.0.X.X.47903 > 10.0.Z.Z.25826: UDP, length 1309
23:24:31.288530 IP 10.0.X.X.47903 > 10.0.Z.Z.25826: UDP, length 1293
23:25:01.273344 IP 10.0.X.X.47903 > 10.0.Z.Z.25826: UDP, length 1318
23:25:31.257782 IP 10.0.X.X.47903 > 10.0.Z.Z.25826: UDP, length 1300

(30s approx)

Now, I added interface and disk. (CPU + 3 SNMP OIDs + MEMORY + DISK +
INTERFACE)

23:26:31.466675 IP 10.0.X.X.48354 > 10.0.Z.Z.25826: UDP, length 1328
23:26:41.465791 IP 10.0.X.X.48354 > 10.0.Z.Z.25826: UDP, length 1301
23:26:51.465875 IP 10.0.X.X.48354 > 10.0.Z.Z.25826: UDP, length 1306
23:27:01.511527 IP 10.0.X.X.48354 > 10.0.Z.Z.25826: UDP, length 1292

(10s approx)

This obviously means the more data, the faster you fill the buffer, the
more often you send the metrics.

All these tests are with the default value for queues/buffers/limits.

I am going to play with those values now and compare the results to these.


I'll update again later.

Joel.
