Don't find Filesystem / percent

[Arethusa]

Hello,

I try the new check_mk input on grafana (instead of pnp nagios), and that works, thank you for that.

However, I have some differences:

On 2.0.0p11 (CRE) With pnp-nagios, I can watch the % usage for Filesystem / with label fs_used_percent.

On 2.0.0p14 (CRE) With grafana plugin, I don’t see fs_used_percent

I don’t have this problem with RAM

On 2.0.0p11 (CRE) With pnp-nagios, I have → mem_used_percent
On 2.0.0p14 (CRE) With grafana plugin, I have → RAM used %

The Metric don’t have the same name, but it’s not a problem ^^

So, do you know why I don’t have fs_used_percent with Grafana plugin with 2.0.0p14 ?

Thank you.

Maybe this werk has fixed the issue. Worth a try.

Hello,
Thank you for suggestion.

I upgrade check_mk 2.0.0p14 to 2.0.0p16 (and the agent too).

However, the problem is the same.

Thank you.

There is a simple solution for this problem. CMK datasource only shows metrics where a graph is defined for. This is really strange
For this problem with the filesystem percentage i have the following as solution.
Create a file “filesystem.py” inside your site under “~/local/share/check_mk/web/plugins/metrics/” with the following content.

#!/usr/bin/env python3
from cmk.gui.plugins.metrics import (
    graph_info,
)

graph_info["fs_used_percent"] = {
    "title": _("Filesystem usage in percent"),
    "metrics": [
        ("fs_used_percent", "area"),
    ],
    "range": (0, 100),
}

Now you should also have a own graph for every filesystem like this one.

And inside Grafana you can select a metric like shown here.

Hello, thank you for suggestion,

However I never use Python and maybe I do something wrong.

I go on :
/opt/omd/sites/OMD/local/share/check_mk/web/plugins/metrics

Then I Create the script with chmod +x.

I have this error:

# ./filesystem.py 
Traceback (most recent call last):
  File "./filesystem.py", line 2, in <module>
    from cmk.gui.plugins.metrics import (
ImportError: No module named 'cmk'

I think I have a good version:

# python -V
Python 2.7.13

# python3 -V
Python 3.5.3

Any ideas ?

Thank you.

@Arethusa

Then I Create the script with chmod +x.

why this? The script don’t need to be executed. You only have to create the file as site user not as root. And now you should see a percent graph for your filesystem.
Then you can also select the percent value in Grafana.

That works !

Thank you for advisement and your availability.
