Open Stack

Cool, but using nagios or the like to trigger app level actions is not what I'm primarily interested in. Mostly the reverse. Its for the app definition to provide the information nessisary for a monitoring system to report to the user when something is very wrong and needs intervention. For example, the website is unresponsive because the backend database server in the demo goes offline, or the maximum number of servers is already been reached and the site responsiveness is bad due to excessive load. Murano doesn't do that currently, does it?

Thanks,
Kevin

Here is the way how we do VM level monitoring in application catalog. There is an application Nagios which will deploy a Nagios VM to the user tenant. And this Nagios application exposes abstracted monitoring app interface to add probes and checks. Another application, Ceilometer Alarm also allows you to use the same monitoring interface to add check for a VM.

Demo is here: https://www.youtube.com/watch?v=OvPpJd0EOFw

As usual Heat is used under the hood for infrastructure level management. You can add other monitoring apps like Zabbix (https://github.com/openstack/murano-apps/tree/master/ZabbixAgent/package, https://github.com/openstack/murano-apps/tree/master/ZabbixServer/package)

It totally depends on how much experience you think a tenant user has...

If we're talking about devops, they tend to have the skills to stand up a configuration management server, a monitoring server, and manage everything via config management.

If tenant users are research scientists, like some of ours, its a fair amount of work to manage nagios without config management, and config management is way more effort then most researchers want to put into learning. That's where an app catalog becomes important, and something like monitoring as a service starts to become interesting....

Thanks,
Kevin

I don't really understand why Nagios-as-a-Service would be useful to
operators. I mean, operators install their monitoring system of choice
via their configuration management tool of choice -- Ansible, SaltStack,
Puppet, Chef, etc.

Frankly, so do tenants. Tenants install software on their images using
configuration management tools like mentioned above... I don't see a
reason to have Nagios-as-a-Service for tenants either.

Not really. It's typically a simple apt-get install nagios-nrpe-plugins
on client VMs along with an apt-get install nagios-server on one or more
monitoring system VMs. Again, have configuration management systems
inject whatever check scripts you want paired with the ones that already
come with nagios-nrpe-plugins package.

I guess I just don't see this being in the realm of OpenStack. Or at
least, not more than something like a Murano application manifest which
is almost what you are describing above.

I don't see the need for this service, sorry. Not everything needs to be
re-invented as a RESTful Python service endpoint...

Best,
