snmp_exporter version: output of `snmp_exporter -version`

What device/snmpwalk OID are you using?

Synology MIB

If this is a new device, please link to the MIB(s).

It's not a new device, i already monitoring this synologys before. https://global.download.synology.com/download/Document/Software/DeveloperGuide/Firmware/DSM/All/enu/Synology_MIB_File.zip

What did you do that produced an error?

I don't change settings, and i have this issue, this is my prometheus config file about synology:

job_name: 'snmp-exporter-synology' honor_timestamps: true scrape_interval: 10m scrape_timeout: 60s static_configs:
- targets: # SNMP devices
  - 10.1.1.5
  - 10.1.1.20
  - 10.4.0.2
    - 10.0.1.4
    
    - 10.0.1.3
    
    - 10.0.1.5
    
    metrics_path: /snmp params: module: [synology] relabel_configs:
- source_labels: [address] target_label: __param_target
- source_labels: [__param_target] target_label: instance
- target_label: address replacement: 10.0.1.241:9116 # The SNMP exporter's real hostname:port.

What did you expect to see?

My targets up and alerts on, like it was a few months ago

What did you see instead?

@davidepellegrini, did you figure out how to solve this issue?

cdalvaro commented 2 years ago

I managed to fix this issue by setting network_mode: host on my docker-compose file for the snmp-exporter service.

davidepellegrini commented 2 years ago

@cdalvaro I have fixed this issue by change the scrape interval from 60 seconds to 120 seconds. I will try your suggestion too, thanks for your reply.
