I’ve been using the SNMP collector against a couple of switches but haven’t been able to get the OID for system uptime to work. snmpwalk works fine: > snmpwalk -t 20 -O fn -v 2c -c netdata 192.168.178.3 .1.3.6.1.2.1.1.3 returns: > .1.3.6.1.2.1.1.3.0 = Timeticks: (6365400) 17:40:54.00 but the graphs say ‘no data’ ands running the module in debug mode returns: > [DEBUG] snmp[GS110TPP\_switch] collect.go:49 skipping OID ‘1.3.6.1.2.1.1.3’ (unsupported type ‘NoSuchInstance’) and then: > BEGIN ‘snmp\_GS110TPP\_switch.snmp\_switch.management.uptime’ > SET ‘Switch Uptime’ = > END My snmp.conf has two jobs, one for each switch. And the config for one looks like this: > - name: GS110TPP switch > update\_every: 5 > hostname: “192.168.178.3” > community: netdata > options: > version: 2 > charts: > - id: “snmp\_switch.bandwidth\_port.GS110TPP” > title: “GS110TPP Switch Bandwidth for port” > units: “MiB/s” > type: “area” > family: “ports” > multiply\_range: [1, 10] > dimensions: > - name: “in” > oid: “1.3.6.1.2.1.2.2.1.10.” > algorithm: “incremental” > multiplier: 8 > divisor: 1000000 > - name: “out” > oid: “1.3.6.1.2.1.2.2.1.16.” > algorithm: “incremental” > multiplier: 8 > divisor: 1000000 > > - id: “snmp\_switch.management.uptime.GS110TPP” > title: “GS110TPP Switch Uptime” > units: “percent” > type: “line” > family: “switch\_management” > dimensions: > - name: “Switch Uptime” > oid: “1.3.6.1.2.1.1.3” > algorithm: “absolute” The port bandwidth counters work fine AFAIK, so I’m not sure what I’m doing wrong with the uptime one as I believe the collector should handle TIMETICKS. ---

I believe you need to put in `1.3.6.1.2.1.1.3.0`, the result of SNMP walk. I don’t see a `multiply_range` for the switch Uptime, so it will simply do an SNMP GET of `1.3.6.1.2.1.1.3`, which doesn’t exist (the .0 at the end is the issue I think). Also, in the docs I see `multiply_range` together with oids that don’t have the trailing `.` that you have here. Do the port in/out stats work despite this? ---

@Christopher_Akritid1 Thanks for that. I knew it was something simple! I guess the question now is how to get the chart to display/convert timeticks to a nice format like days/hours/minutes etc?? 🙂 Yes, the trailing dot was required (I couldn’t get it to work any other way) when I first set this up a while back (even though the docs didn’t say so) but I just tested and it works fine either way. ---

Use a multiplier/divisor to convert the value to seconds if needed.
