Running v2 extension on a certain ActiveGate inside a group?

[AntonioSousa]

For scalability reasons, I have ActiveGate groups with more than one ActiveGate.

Now, I have several EF2 extensions running on those groups, and it works well.

But, now I need to have a particular EF2 extension running on a specific ActiveGate, for several reasons.

It would be great to have an ActiveGate belong to several groups, but that is not possible. I also cannot change the group because that would break the other extensions.

In EF1, I just had to install it in the ActiveGate I wanted...

What would be the best way to achieve this with EF2? Using fastcheck?

Using fastcheck would indeed be the way to solve this. I’d go with checking for the existence of a specific file for example if I were you, that way you don’t have to hardcode the AG name into the extension.

@Mike_L,

Never had used fastcheck before, and it seems to work well. I do believe though that we need an AG to eventually belong to more than one group: https://community.dynatrace.com/t5/Product-ideas/Activegate-belonging-to-several-groups/idi-p/259362

Interestingly, I discovered that it only runs the first time. It I update a monitoring configuration, it doesn't run again. But I can live with that 😁

So, when what cases does fastcheck run again? When restarting the extensions module? In any other cases?

Whenever the cluster needs to re-validate what AG will execute the extension, so during communication loss and when you go over the hard usage limit.
