Prometheus SNMP Exporter: Network Monitoring Tutorial!

[@douglaspayne5029]

This is an excellent video, well thought out, well presented, perfectly explained. This will help a lot of people! How about if you have 250 devices? This solution seems like it would take a long time. Perhaps if I were a cat with 7 lives then I could use 3 of them to configure Prometheus and get it to work in a medium sized business with about 65 devices across several locations.

[@distrodomain]

In my case I’m generating the Prometheus config dynamically from an ansible inventory where we have all our devices so it speeds up the process for that, and on the grafana side we have a dynamic dashboard, thank you for watching !

[@Sonnenblume114]

Ok nevermind, it works. Thanks for this Video i watched it maybe 100 times this week but now it works. :D

[@distrodomain]

I'm glad it works! yes it's a bit tricky the whole setup, once you understand the basic parts of the puzzle it get easier, thank you for watching!

[@MmauricioHirsch]

Thank you very much for sharing your knowledge, it is helping me a lot. The tutorial was really good! I'm looking from here in Brazil.

I'm glad it was helpful! thank you for watching!

Thanks for the guide, seems like "- target_label: __ address__ " in the description has been screwed up by the formatting and changed to "- target_label: _ address_ " (_ changes the text formatting to italic). Sorry for the extra spaces, couldn't figure out how to do the proper formatting my self... One suggestion would be to create a GitHub gist instead with the code

[@distrodomain]

I'm working on this to have a better formated code blocks, thank you for the suggestion and for watching!

[@mancobasanele4520]

Great guide, how to enable Prometheus to walk the entire device so I can also get metrics for CPU, memory, icmpOutErrors and temperature

[@distrodomain]

you can add top level mib to the list to crawl like "icmp" parent that includes: icmpInMsgs icmpInErrors icmpInDestUnreachs icmpInTimeExcds icmpInParmProbs icmpInSrcQuenchs icmpInRedirects icmpInEchos icmpInEchoReps icmpInTimestamps icmpInTimestampReps icmpInAddrMasks icmpInAddrMaskReps icmpOutMsgs icmpOutErrors icmpOutDestUnreachs icmpOutTimeExcds icmpOutParmProbs icmpOutSrcQuenchs icmpOutRedirects icmpOutEchos icmpOutEchoReps icmpOutTimestamps icmpOutTimestampReps icmpOutAddrMasks icmpOutAddrMaskReps icmpStatsTable icmpMsgStatsTable you can use an OID reference table to check each parent, let me know if it's helpful, thank you for watching

[@piotrnasiadka1671]

Hi can someone help me i did a tutorial and it's working but I also need in grafan a information about what is the temperature of my ups. I think I need to and a question for snnmp to get that information

[@damolaazeez3518]

Thank you for this. Would this process work with Cisco devices.

[@distrodomain]

yes this works with any device that supports snmp, Thank you for watching!

[@TheBroadcastEngineer]

I'm running into this error when I'm trying to run *make generator mibs* make: go: No such file or directory make: *** [Makefile:87: generator] Error 127 I've searched high and low on KZbin and Google... nothing... everyone who is doing this tutorial has no problems... Do you have any suggestions? Thanks!

[@distrodomain]

You are missing the go programing language, you need to install the devel libraries, if you are on ubuntu try apt install gccgo-go or apt install golang-go thank you for watching

[@TheBroadcastEngineer]

@@distrodomain awesome I’ll give that a shot on Monday, thank you!

[@TheBroadcastEngineer]

@@distrodomain thank you so much! I missed that step completely and it’s working now.

[@stefhaniemilagrosjaramillo2299]

Hi that is only possible with snmp v3? its not allow to v1 or v2?

[@mizatto]

I make it work with v2, since I could not made it work with v3

[@distrodomain]

Yes it works with v1 and v2, I do recommend using v3 tho, thank you for watching!

[@jakebenjamin8895]

Do you have a discord or anything similar for community help ? Can't seem to get this to work with custom mibs for a arista switch

[@distrodomain]

The discord is coming soon, and actually I will be adding some arista switches to my system soon, mibs you are probably good with what comes on the generator, what you need to look for is what OIDs you want to scrape like interfaces, or ifHCInOctets, under ifmib, or are you having issue generating the config, thank you for watching!

what error are you getting?

Hi Bro, I wan to add module fortigate to snmp_exporter, i have MIB file Fortigate but run the generate not detected

[@distrodomain]

put the fortinet mibs in the mibs folder, then on your generator conf, you need to put what oids you want to include in the config to scrape, then generate the config again, let me know if it gives you any errors, thank you for watching!

[@overbytex2]

lol, not so straight forward huh :D generator ruins it
