Hello,

My Netdata version is v1.44.1 running on Ubuntu 22.04

I want to switch from python.d to go.d web\_log plugin but I’m not able to find a way to reproduce my current python.d config which is the following

```auto
apache_log2:
  name: redacted
  path: "/home/redacted/log/apache2/access.log"
  filter:
    exclude: status.html
apache_log_lb:
  name: Log_lb
  path: "/home/redacted/log/apache2/access.log"
  filter:
    include: status.html

```

The idea of this config is to have 2 graph, one for the users requests, and another for the LB requests, which are checking the status of the serveur using status.html URL.

I tried multiple config without luck, and the documentation does not give a full example of the url\_patterns syntax.

For example:

```auto
---
jobs:
  - name: redacted
    path: /home/redacted/log/apache2/access.log
    url_patterns:
      - name: user_log
        pattern: !status.html
  - name: Log_lb
    path: /home/redacted/log/apache2/access.log
    url_patterns:
      - name: lb_log
        pattern: status.html

```

Give me the following error:

```auto
DBG jobmgr/manager.go:127 received config group ('/etc/netdata/go.d/web_log.conf'): 2 jobs (added: 2, removed: 0) component="job manager"

REPORT_JOB_STATUS 'web_log' 'Log_lb_13677350966184747916' 'error' 0 'job detection failed, stopping it'

```

I’m a bit lost, could anyone help me?

Thanks

@DeWaRs1206 hey

1. It is not `pattern` but `match`.
2. `match` pattern - see [matcher syntax](https://github.com/netdata/go.d.plugin/tree/master/pkg/matcher#supported-format).

```yaml
  - name: Log_lb
    path: /home/redacted/log/apache2/access.log
    url_patterns:
      - name: lb_log
        match: '* *status.html*' # everything that contains `status.html`
      - name: user_log
        match: '!* *status.html*' # everything that doesn't contain `status.html`

```
