<p class="MsoNormal" style="word-break:normal"><span style="font-size:11.0pt;font-family:Calibri">Mistral has a long list of actions that can be used. Specifically, you can use the std.ssh action to execute shell scripts.</span><o:p></o:p></p>

<p class="MsoNormal" style="word-break:normal"><span style="font-size:11.0pt;font-family:Calibri">I’m not sure about the output of the std.ssh, and whether you can get it from the action. I suggest you try it and see how it works.</span><o:p></o:p></p>
<p class="MsoNormal" style="word-break:normal"><span style="font-size:11.0pt;font-family:Calibri">The action is implemented here:

<p class="MsoNormal" style="word-break:normal"><span style="font-size:11.0pt;font-family:Calibri">If std.ssh does not suit your needs, you also have an option to implement and run your own action in Mistral (either as an ssh action or as a python code).

<p class="MsoNormal" style="word-break:normal"><span style="font-size:11.0pt;font-family:Calibri">And BTW, it is not related to your current use case, but we can also add Vitrage actions to Mistral, so the user can access Vitrage information (get topology,
get alarms) from Mistral workflows. </span><o:p></o:p></p>

<p class="MsoNormal" style="word-break:normal"><span style="font-size:11.0pt;font-family:Calibri">Thanks for the explanation, I understand the reasons for not running these checks on a regular basis in Zabbix or other monitoring tools. It makes sense. However,
I don’t want to re-invent the wheel and add to Vitrage functionality that already exists in other projects.

<p class="MsoNormal" style="word-break:normal"><span style="font-size:11.0pt;font-family:Calibri">How about using Mistral for the purpose of manually running these extra checks? If you prepare the script/agent in advance, as well as the Mistral workflow, I
believe that Mistral can successfully execute the check and return the results. I’m not so sure about the UI part, we will have to figure out how and where the user can see the output. But it will save a lot of effort around managing the checks, running a
new service, supporting a new API, etc.</span><o:p></o:p></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri;color:black">The reason I do not think of tools like Zabbix, Nagios, and Prometheus as a tool to run checks is because we need to configure an agent or an exporter.</span><o:p></o:p></p>

running such checks? If you use Zabbix, you can define new triggers that run the new checks, and whenever needed the user can ask to open Zabbix and show the relevant metrics. The format will not be exactly the same as in your example, but it will save a lot
of work and spare you the need to write and manage a new service. </span><o:p></o:p></p>
