# Troubleshooting

## Bad requests (HTTP 400)
|
|
|
|
This role downloads checksums from the Github project to verify the integrity of artifacts installed on your servers. When downloading the checksums, a "bad request" error might occur.
|
|
|
|
This happens in environments which (knowningly or unknowling) use the [netrc mechanism](https://www.gnu.org/software/inetutils/manual/html_node/The-_002enetrc-file.html) to auto-login into servers.
|
|
|
|
Unless netrc is needed by your playbook and ansible roles, please unset the var like so:
|
|
|
|
```
|
|
$ NETRC= ansible-playbook ...
|
|
```
|
|
|
|
Or:
|
|
|
|
```
|
|
$ export NETRC=
|
|
$ ansible-playbook ...
|
|
```

## node_exporter doesn't report data from textfile collector
|
|
|
|
There are 3 potential issues why node_exporter doesn't pick up data:
|
|
|
|
1. Duplicated metrics across multiple files.
|
|
2. File is not readable by node_exporter process.
|
|
3. Textfile collector is not enabled.
|
|
|
|
Solving first possibility is out of scope of the role as data is created somewhere else. When creating that data ensure
|
|
files are readable by `node-exp` user. To get access to the directory with files your process needs to be in `node-exp`
|
|
group.
|
|
|
|
Lastly ansible role misconfiguration can also lead to data not being picked up. Check if `node_exporter` textfile
|
|
collector is enabled in `node_exporter_enabled_collectors` as follows:
|
|
|
|
```yaml
|
|
node_exporter_enabled_collectors:
|
|
- textfile:
|
|
directory: "{{ node_exporter_textfile_dir }}"
|
|
```
|
|
|
|
__note___: `node_exporter_textfile_dir` variable is only responsible for creating a directory not enabling a collector.
