# Monitoring Drupal

### Install the Nagios Module

```bash

drush pm-download nagios

drush -y pm-enable nagios

drush cache-clear all

```

### Manual (Web UI) configuration

*Note: CLI configuration* *is much faster, see below.*

-   Go to Drupal's **Configuration menu » Nagios Monitoring.**

-   Insert a random Unique ID.

-   Check "Enable status page?"

-   Under "Thresholds", set "Cron duration" to "480" (8 hours) and

    "Minimum report severity" to CRITICAL.

-   Go to **Modules menu**.

-   Next to "CiviCRM", check "Ignore from Nagios" and press "Save".

### CLI Configuration

-   Paste this on the command line:

```bash

drush vset nagios_cron_duration '480'

drush vset nagios_enable_nagios 1

drush vset nagios_enable_status_page 1

drush vset nagios_enable_status_page_get 0

drush vset nagios_func_cron 1

drush vset nagios_status_ok_value '0'

drush vset nagios_status_unknown_value '3'

drush vset nagios_status_warning_value '1'

drush vset --format=json nagios_ignored_modules '{"civicrm":true}'

# This sets a random site key

# Ensure pwgen is installed

drush vset nagios_ua `pwgen -s 32 1`

```

Icinga Configuration

--------------------

-   Log into the Icinga server: `ssh icinga`

-   If necessary, define the new host by making a copy of an existing

    host file in `/etc/icinga2/conf.d/hosts`.

-   Add the

    line: `vars.drupal_site_id = "<unique site id here>" (unique ID from /admin/config/system/nagios)`

-   TODO: Indicate if SSL is required and how to indicate it.

-   Test your syntax with: `service icinga2 checkconfig`.

-   Restart Icinga: `service icinga2 restart`
