Hi Ben,
I ran another VM and used roles:
- https://github.com/cloudalchemy/ansible-snmp-exporter
- https://github.com/cloudalchemy/ansible-prometheus
along with Grafana. Prometheus, node.exporter and Grafana work as intended
(as before).
However, when I try to enable snmp_exporter:
- job_name: snmp
metrics_path: /snmp
params:
module:
- if_mib
relabel_configs:
- source_labels:
- __address__
target_label: __param_target
- source_labels:
- __param_target
target_label: instance
- replacement: 127.0.0.1:9116
target_label: __address__
static_configs:
- targets:
- 192.168.10.187
I get error in syslog:
Aug 21 14:43:23 monnew snmp_exporter[363]: level=info
ts=2020-08-21T12:43:23.189Z caller=collector.go:224 module=if_mib
target=192.168.10.187 msg="Error scraping target" err="scrape canceled
(possible timeout) getting target 192.168.10.187"
snmp is enabled on device on 192.168.10.187. I tried snmp version 2c and 3
but the error message is the same. I can connect on that IP:port from
prometheus/snmp_exporter node:
root@monnew:~# telnet 192.168.10.187 161
Trying 192.168.10.187...
Connected to 192.168.10.187.
Escape character is '^]'.
Port 9116 is opened on localhost on prometheus/snmp_exporter node:
root@monnew:/etc/snmp_exporter# netstat -na|grep 9116
tcp 0 0 127.0.0.1:35274 127.0.0.1:9116

Trying 127.0.0.1...
Connected to 127.0.0.1.

What I am missing here is that generator thing. I didn't install any mibs
in this case, and, from what I see in Ansible role, no mibs or generator
has been set/run.
Instead, snmp.yml file is being pulled from remote location:
"https://raw.githubusercontent.com/prometheus/snmp_exporter/v{{
snmp_exporter_version }}/snmp.yml"
Could you shed some light here, because I am obviously missing some step
along the way.
Thanks in advance!
Best regards,
Mario.
