Questions on [[inputs.internet_speed]]

Telegraf
1

Hi all,

I have activated the measurement of an internet connection with the following code:

# Monitors internet speed using speedtest.net service
[[inputs.internet_speed]]
## Sets if runs file download test
## Default: false
# enable_file_download = false

I have the impression that it really slows down my internet speed. Any similar obervations?

When I look at the data, the test is run every minute. Is it possible to change the run interval? e.g. to 15 minutes?

Thanks for your help!

By default Telegraf will collect all inputs every 10 seconds. For the internet speed test, this is not very useful and results in a very, very slow connection. You can see an interval on a per-input plugin basis. I would suggest setting the following to only run the internet_speed test very hour:

[[inputs.internet_speed]]
    interval = "1h"

I was not successful with this. :frowning: After adding

interval = "15m"

it is no longer running at all. At least no values arrive in the database. Even after restarting Telegraf.

Any other ideas?

You are going to need to provide some more details. At the very least provide the full config you used + the Telegraf logs.

For example, I used this config:

[agent]
  omit_hostname = true

[[outputs.file]]

[[inputs.internet_speed]]
    interval = "15m"

./telegraf --config config.toml --debug
