this is my snmp.yml，I have used a new template, sysuptime can be obtained, and ifnumber can also be obtained normally, but sysname has been invalidated. What is the reason for this? My snmp\_ Exporter startup did not see relevant error logs

I don’t have this problem. My problem is described at github .com/prometheus/snmp\_exporter/discussions/1202#discussioncomment-10021820

I will repeat that information here:

> We seem to be having a similar problem with about half of our Ethernet switches in one datacenter. But the problem seems randomly distributed between Cisco and Juniper switches. I’ve set the `scrape_interval` to be 300s and the `scrape_timeout` to be 200s, but almost all of the failures have a very suspicious looking `scan_duration` of right around 20s. We are only querying `if_mib`.

Is there any other information that I can provide?

This appears to be related to github. com/prometheus/snmp\_exporter/issues/367 and github. com/prometheus/snmp\_exporter/issues/850 but both of those issues were closed because the problem was supposedly fixed.

I’ve also posted about this issue at old.reddit. com/r/PrometheusMonitoring/comments/1e0qjsz/differences\_between\_snmp\_exporter\_and\_snmpwalk/? and in the CNCF Slack channel Prometheus at cloud-native.slack. com/archives/C167KFM6C/p1720710093899439

Are there any other places that people would suggest that could be good resources for this question?

Or any other suggestions in general?

Thanks!

PS: Sorry that I had to break all the links, but apparently new users aren’t allowed to post links here.
