Monitored Processes List
|
|
========================
|
|
|
|
The monitored processes list allows user, through the configuration
|
|
file, to group processes and quickly show if the number of running
|
|
processes is not good.
|
|
|
|
.. image:: ../_static/monitored.png
|
|
|
|
Each item is defined by:
|
|
|
|
- ``description``: description of the processes (max 16 chars).
|
|
- ``regex``: regular expression of the processes to monitor.
|
|
- ``command``: (optional) full path to shell command/script for extended
|
|
- stat. Should return a single line string. Use with caution.
|
|
- ``countmin``: (optional) minimal number of processes. A warning will
|
|
- be displayed if number of processes < count.
|
|
- ``countmax``: (optional) maximum number of processes. A warning will
|
|
be displayed if number of processes > count.
|
|
|
|
Up to ``10`` items can be defined.
|
|
|
|
For example, if you want to monitor the Nginx processes on a web server,
|
|
the following definition should do the job:
|
|
|
|
.. code-block:: ini
|
|
|
|
[monitor]
|
|
list_1_description=Nginx server
|
|
list_1_regex=.*nginx.*
|
|
list_1_command=nginx -v
|
|
list_1_countmin=1
|
|
list_1_countmax=4
|
|
|
|
If you also want to monitor the PHP-FPM daemon processes, you should add
|
|
another item:
|
|
|
|
.. code-block:: ini
|
|
|
|
[monitor]
|
|
list_1_description=Nginx server
|
|
list_1_regex=.*nginx.*
|
|
list_1_command=nginx -v
|
|
list_1_countmin=1
|
|
list_1_countmax=4
|
|
list_2_description=PHP-FPM
|
|
list_2_regex=.*php-fpm.*
|
|
list_2_countmin=1
|
|
list_2_countmax=20
|
|
|
|
In client/server mode, the list is defined on the server side.
|
|
A new method, called `getAllMonitored`, is available in the APIs and
|
|
get the JSON representation of the monitored processes list.
|
|
|
|
Alerts are set as following:
|
|
|
|
================= ============
|
|
# of process Status
|
|
================= ============
|
|
``0`` ``CRITICAL``
|
|
``min < p < max`` ``OK``
|
|
``p > max`` ``WARNING``
|
|
================= ============
