Hi, Could you please confirm how to add alias names for multiple agents separately in Inputs.snmp configuration? Here is the list of agents [[inputs.snmp]] agents = [ “udp://11.12.21.21:161”, “udp://11.12.21.22:161”, “udp://11.12.21.23:161”, “udp://11.12.21.24:161”, “udp://11.12.21.25:161”, “udp://11.12.21.26:161”, “udp://11.12.21.27:161”, “udp://11.12.21.28:161” ] ---

@Hipska could you please provide some solution on this. I tried following options but it doesn’t work. Option-1 [[inputs.snmp]] agents = [“udp://11.12.21.21:161”] alias = “US-server” agents=[“udp://11.12.21.21:161”], alias = “UK-server” Option-2 [[inputs.snmp]] agents = [“udp://11.12.21.21:161”] alias = “US-server” [[inputs.snmp]] agents=[“udp://11.12.21.21:161”], alias = “UK-server” ---

Option 2 looks indeed how you should proceed. ---

Thank you for your quick response, I dont see agent\_host column get change with alias in the influxDB if I choose option-2. Do I need to enable any additional parameter within Telegraf? Thanks, ---

I don’t understand your question, but you can always run `telegraf --test` with your config to see if you are getting the correct metrics. ---

Sorry if my above query confusing you. I mean even after adding the alias it still sending the IP address in influxDB instead of hostname of Alias. Do I need to modify anything within Telegraf for the Agent\_Host in order to send the alias names instead of IP as an output to the InfluxDB? ---

> [@Manju](#): > > Do I need to modify anything within Telegraf for the Agent\_Host in order to send the alias names instead of IP as an output to the InfluxDB? This is very different question than your original question. `alias` is used to name and distinguish different plugins from each other. This is especially helpful for logging. It is not used to rename metrics or change the data when sending it. I think the easiest method to add your “alias” to your metrics is to add a new tag for each `snmp` output: ```toml [[inputs.snmp]] agents=["udp://11.12.21.21:161"] tags = {alias = "UK-server"} ``` You could also use a processor to swap out the `agent_host` for your alias if you didn’t want antoher tag. ---

Thank you for the solution @Hipska. Now I am getting necessary data after adding the tag values. ---

@Hipska, I see the alias tab created in influxDB but currently only one agent name is appearing. Out of 10 agents, the last agents displaying with alias name. Do I need to modify anything in the Telegraf in presenting all agents alias names ---

Please don’t @ me anymore! What does your current config look like? Did you change the value of the tags for each input config? (Please also put your config inside a code block for better readability) ---

Yes I added the tags for each agent in the input.snmp, here is the configuration. ```auto [global_tags] # dc = "us-east-1" # will tag all metrics with dc=us-east-1 # rack = "1a" ## Environment variables can be used as tags, and throughout the config file #user = "$USER" ``` ```auto [agent] ## Default data collection interval for all inputs #interval = "10s" ## Rounds collection interval to 'interval' ## ie, if interval="10s" then always collect on :00, :10, :20, etc. round_interval = true ``` ```auto hostname = "" ## If set to true, do no set the "host" tag in the telegraf agent. omit_hostname = false ## Method of translating SNMP objects. Can be "netsnmp" (deprecated) which ## translates by calling external programs snmptranslate and snmptable, ## or "gosmi" which translates using the built-in gosmi library. # snmp_translator = "netsnmp" ## Name of the file to load the state of plugins from and store the state to. ## If uncommented and not empty, this file will be used to save the state of ## stateful plugins on termination of Telegraf.

Okay, I only see a table to be collected for the device US-SBC05, I assume that is also the one that you can find in InfluxDB? You also need to specify which tables/fields to be collected for the other devices… ---
