Evaluating checkmk 2.0.0p1 CFE running on Ubuntu 20.04 and trying to monitor Cisco Catalyst 9300 and 9500 switches running IOS XE 16.12.03a using SNMP v2. I’m seeing “item not found…” events at random intervals - always on interfaces where it’s pulling SFP DOM data (temp, rx/tx power). They just come and go for no apparent reason.
Loving what I see so far with checkmk and I’m looking to replace both my Solarwinds instances, but if I can’t reliably monitor switch interface data it’s just not going to work for me.
BTW - I sent an email to your marketing address two days ago asking what support resources are available during an evaluation and never heard back, so here I am. Might want to look into that as first impressions do matter.
