SNMP performance monitoring / metrics

General
1

Hi all!

Just out of curiosity - would checkmk scale up to (and more than) 1000 devices / 100.000+ interfaces monitoring for

  • using SNMP v2 and v3
  • interface stats (bytes in/out, discards, errors, multi & unic., …)
  • up / down status (admin / oper)
  • 60 seconds resolution / shedule
  • write all the metric data to influxdb (using the new native influxdb implemenation maybe)
  • alert by various cirterias (interface saturation, up/down, errors in time, …)

using an distributed setup ( ~ aprox 60 locations )?

many thx & br
Oliver

If you can place a monitoring site in every of the 60 locations, then definitively yes.
If the monitoring sites have to run in a central location network latency plays a big role in SNMP monitoring.

Hi @lnxshell,

welcome to this community!

@r.sander already said it - if you distribute the monitoring load to all those locations - shouldn’t be a problem at all.

1000 devices also should not be a big problem on one or only a few sites, with the caveat of what Robert wrote about latency and also what exactly is being monitored.

Regarding all things SNMP I can highly recommend this article series by my colleagues Alex and Timo: Blog | SNMP Monitoring | Checkmk

THx for your answers!

Yes, the source of the snmp poll would always be in the local network (also placing a locale site vm would be fine). So we should be “safe” :slight_smile:

What about transfering/sending the “ourcome” of data (specially metrics) to a central location for storing them in InfluxDB for example?

Hi,
if your remote CheckMK server are able to connet to Influx, you can configure cmc on each site to write in your central time series database.
Best regards,

Hi,

ok, so there is no (not yet ^^) integrated transport (using livestatus proxy tcp pools for example) from the remote site to the “central site”? And what about caching? Would we face dataloss (metrics) if the connection is broken for some minutes?

Thx & br
Oliver
