Applications Monitoring Process
|
|
===============================
|
|
|
|
Thanks to Glances and its AMP module, you can add specific monitoring to
|
|
running processes. AMPs are defined in the Glances [configuration file](http://glances.readthedocs.io/en/stable/config.html).
|
|
|
|
You can disable AMP using the ``--disable-amps`` option or pressing the
|
|
``A`` key.
|
|
|
|
Simple AMP
|
|
----------
|
|
|
|
For example, a simple AMP that monitor the CPU/MEM of all Python
|
|
processes can be defined as follows:
|
|
|
|
.. code-block:: ini
|
|
|
|
[amp_python]
|
|
enable=true
|
|
regex=.*python.*
|
|
refresh=3
|
|
|
|
Every 3 seconds (``refresh``) and if the ``enable`` key is true, Glances
|
|
will filter the running processes list thanks to the ``.*python.*``
|
|
regular expression (``regex``).
|
|
|
|
The default behavior for an AMP is to display the number of matching
|
|
processes, CPU and MEM:
|
|
|
|
.. image:: ../_static/amp-python.png
|
|
|
|
You can also define the minimum (``countmin``) and/or maximum
|
|
(``countmax``) process number. For example:
|
|
|
|
.. code-block:: ini
|
|
|
|
[amp_python]
|
|
enable=true
|
|
regex=.*python.*
|
|
refresh=3
|
|
countmin=1
|
|
countmax=2
|
|
|
|
With this configuration, if the number of running Python scripts is
|
|
higher than 2, then the AMP is displayed with a purple color (red if
|
|
less than countmin):
|
|
|
|
.. image:: ../_static/amp-python-warning.png
|
|
|
|
User defined AMP
|
|
----------------
|
|
|
|
If you need to execute a specific command line, you can use the
|
|
``command`` option. For example, if you want to display the Dropbox
|
|
process status, you can define the following section in the Glances
|
|
configuration file:
|
|
|
|
.. code-block:: ini
|
|
|
|
[amp_dropbox]
|
|
# Use the default AMP (no dedicated AMP Python script)
|
|
enable=true
|
|
regex=.*dropbox.*
|
|
refresh=3
|
|
one_line=false
|
|
command=dropbox status
|
|
countmin=1
|
|
|
|
The ``dropbox status`` command line will be executed and displayed in
|
|
the Glances UI:
|
|
|
|
.. image:: ../_static/amp-dropbox.png
|
|
|
|
You can force Glances to display the result in one line setting
|
|
``one_line`` to true.
|
|
|
|
Embedded AMP
|
|
------------
|
|
|
|
Glances provides some specific AMP scripts (replacing the ``command``
|
|
line). You can write your own AMP script to fill your needs. AMP scripts
|
|
are located in the ``amps`` folder and should be named ``glances_*.py``.
|
|
An AMP script define an Amp class (``GlancesAmp``) with a mandatory
|
|
update method. The update method call the ``set_result`` method to set
|
|
the AMP return string. The return string is a string with one or more
|
|
line (\n between lines). To enable it, the configuration file section
|
|
should be named ``[amp_*]``.
|
|
|
|
For example, if you want to enable the Nginx AMP, the following
|
|
definition should do the job (Nginx AMP is provided by the Glances team
|
|
as an example):
|
|
|
|
.. code-block:: ini
|
|
|
|
[amp_nginx]
|
|
enable=true
|
|
regex=\/usr\/sbin\/nginx
|
|
refresh=60
|
|
one_line=false
|
|
status_url=http://localhost/nginx_status
|
|
|
|
Here's the result:
|
|
|
|
.. image:: ../_static/amps.png
|
|
|
|
In client/server mode, the AMP list is defined on the server side.
