The dashboard is not showing any data when I run the telegraf -test I get the error but I don't believe these related to the dashboard:
_
Cannot find module (IF-MIB): At line 1 in (none)
IF-MIB::ifTable: Unknown Object Identifier_

Running it on Ubuntu 16.04, any suggestions what I'm doing wrong?

Can you say how to monitor iops with this method? thx

When i run the telegraf scrapper it spits out
2021-11-25T13:05:00Z E! [inputs.snmp] Error in plugin: initializing table : translating: exec: "snmptranslate": executable file not found in %PATH%

Telegraf Configuration for Synology NAS monitoring via SNMP

These output definitions are only required if not already existing.

This dashboard does not depend on the specific output configuration - only

that an InfluxDB database is used.

###############################################################################

OUTPUT PLUGINS

###############################################################################

Configuration for influxdb server to send metrics to

[[outputs.influxdb]]

The full HTTP or UDP endpoint URL for your InfluxDB instance.

Multiple urls can be specified as part of the same cluster,

this means that only ONE of the urls will be written to each interval.

urls = ["http://172.16.0.207:8086"] # required

The target database for metrics (telegraf will create it if not exists).

database = "syno" # required

Retention policy to write to. Empty string writes to the default rp.

retention_policy = ""

Write consistency (clusters only), can be: "any", "one", "quorum", "all"

write_consistency = "any"
Only part not shown is the username part in outputs

Following your instructions I've got the Synology dashboard working great, thanks for all the work you've done on this!

I'm having a little trouble creating a query in Grafana to pull UPS status information. I've installed all of the Synology MIBs, and see the SYNOLOGY-UPS-MIB.txt, but I can't seem to find the information it's gathering. Would you have any suggestions?

...and yes I have a UPS connected to the Synology, and can see it's information in the Synology gui.

No Data, Synology DashBoard show me. Can you help me ?

I have set up telegraf with snmp, downloaded the Mib files, edited my telegraf.conf file, and setup influx and grafana and everything appeared to work for a day or 2 and then the Traffic data stopped showing up. The history also is not there any more. I don't believe I changed anything relevant, but obviously something has changed. Do you have any suggestions for ways to troubleshoot this? I'm out of ideas.
