Hi all!

I am very new to influxdb and am trying to setup telegraf to poll my network devices via snmp. I currently am failing when trying to test and receive this error:

Error in plugin [inputs.snmp]: initializing table snmp: getting table columns: exec: “snmptable”: executable file not found in $PATH

SNMP inputs config is below:

# # Retrieves SNMP values from remote agents

[[inputs.snmp]]  
agents = [“xxx.xxx.xxx.xxx:161”]  
version = 2  
name = "snmp"  
community = “xxxxxxx”

# 

# 

[[inputs.snmp.field]]  
name = "hostname"  
oid = "1.3.6.1.4.1.9.2.1.3"  
is\_tag = true

# 

# 

[[inputs.snmp.table]]  
name = "snmp"  
inherit\_tags = [“hostname”]  
oid = “1.3.6.1.2.1.31.1.1”

# 

# 

[[inputs.snmp.table.field]]  
name = "ifname"  
oid = "1.3.6.1.2.1.31.1.1.1.1"  
is\_tag = true

I am running the influxdb and telegraf on RHEL

Any pointers in the right direction would be great! I am just starting out so im sure its something configurational

Thanks

Rob

You need to make sure that the `snmptable` executable is in the telegraf users path. Usually that just requires installing the right package, I believe it is `yum install net-snmp-utils` on RHEL.

Daniel that fixed the issue!

however I don’t see the new measurement in influxdb when I do show measurement. I would think to see snmp? Do I need to restart influxdb?

best regards

Rob

I figured it out I had not started telegraf!
