Newbie needs help monitoring printer

Hi. I have just got Grafana up and running with InfluxDB and Telegraf and collecting some stats on my Synology NAS via SNMP. I now want to add my Brother Laser Printer but am having trouble figureing out how to do this. What I have done so far:

  1. snmpwalk on printer and found a MIB that shows the model number
  2. Added the following to my Telegraf conf file:
    #Brother Printer


List of agents to poll

agents = [ “” ]

Polling interval

interval = “60s”

Timeout for each SNMP query.

timeout = “10s”

Number of retries to attempt within timeout.

retries = 3

SNMP version, UAP only supports v1

version = 1

SNMP community string.

community = “public”

The GETBULK max-repetitions parameter

max_repetitions = 10

Measurement name

name = “snmp.bro”

is_tag = true
name = “ModelNumber”
oid = “HOST-RESOURCES-MIB::hrDeviceDescr.1”

  1. Restarted Telegraf and checked my influxDB named homelab.
    No measurements are showing up.

Can someone tell me what I am doing wrong?


Fixed: For anyone else having similar issues, I fixed this by removing the “is_tag = true” line in my telegraf.config. Now it looks like this:


 name = "ModelNumber"
 oid = "HOST-RESOURCES-MIB::hrDeviceDescr.1"

Yes, ando that suggestion makes my monitoring problem solved, but now I also have some another printer not activated error code 30, this is more irritating than this I get help for this to a blog printer not activated error code 30 but the problem is still there.
