description |
The munin core plugin for network interface traffic metric, "if_", registers invalid values on the master side because the configuration phase does not report valid network speed interface. Reports negative range (up.max is negative, while up.min is 0), and thus registers as NaN by the master, even though the node itself sends valid numbers:
# munin-run if_ens3 config
.
.
.
up.min 0
up.max -1000000
up.info Traffic of the ens3 interface. Maximum speed is -1 Mb/s.
down.max -1000000
# munin-run if_ens3
down.value 107758093
up.value 77710387
See also: https://github.com/mail-in-a-box/mailinabox/issues/896
The bug has been fixed upstream:
https://github.com/munin-monitoring/munin/commit/290d5ac2be02ced4d09fda68dc561fcf082c9cbf |
[Impact]
The network interface traffic metric plugin reports invalid values for network speed interface (negative values).
This is the upstream fix for this issue:
https://github.com/munin-monitoring/munin/commit/78c3c3aa
[Test Case]
Install munin and call the plugin checking for the network interface config:
$ multipass launch -n munin-test daily:16.04
$ multipass shell munin-test
$ sudo apt update && sudo apt upgrade -y
$ sudo apt install munin -y
$ sudo munin-run if_ens4 config | tail -n 3
up.max -1000000
up.info Traffic of the ens4 interface. Maximum speed is -1 Mb/s.
down.max -1000000
[Regression Potential]
The risk of a regression is quite small, it is one-line change and it now checks if the value is greater than 0 instead of checking for the size of the returned string. However, if a regression is going to happen it will be in the network interface traffic metric plugin, more specifically regarding the interface speed metric.
