Check if VMs are up or down without having to install oneagent

[ash2]

Hi Team, 

I have two virtual machines, we only need to check if these VMs are up or down. Can anyone please let me know if there is a way to check these VM's availability without having to install oneagent as we do not want to have APM on this?

Thanks,

Hey Ash,

Dynatrace offers a wide range of remote monitoring extensions, integrations and out of the box features. If you want just availability you could use some form of synthetic monitoring. If the VM exposes a HTTP endpoint then you could use a HTTP monitor to ensure functionality and not just availability. Otherwise you could use the NAM synthetics to ping or TCP port test.

Depending on what is hosting these VMs, you could use some form of integration with the VM service. For clouds we have Azure, AWS and GCP integrations that can get some core metrics for you. You can also customize them to ensure you are only capturing metrics of interest, you don't have to capture everything.

If you have another host instrumented that makes calls to these VMs and the traces for those are captured, you could use failure rate metrics to calculate uptime based on successful responses. 

Depending on the environment there are many options, if the above aren't applicable we'll probably need more information about the environment to understand what it is that can be implemented.

Hope this helps!

Hi @ash2 
Looks like you're looking for NAM

Hi @ash2 

• you can monitor the availability of VMs without Oneagent deployments via supported extensions by Dynatrace.
• Check the supported VM technology through Hub.
• Ensure your AGs are able to reach the intended endpoints.
• Add the extension to your environment and the required configuration then you should receive the monitoring signals and as per that you can enable the different alerts.
• there are direct integrations with VMWare, Azure, GCP and other cloud technologies where you don't need to install Oneagent directly on the target VMs.
• you can configure it Under Infrastructure observability.

 

Or 

test the connection and save the configurations > wait few minutes till the monitoring signals being received and configure the required alerts easily.

Regards,

Peter.
