​Data loss occurs when 1 of 2 Security Gateway stop?

[nkobayashi1]

Hi,

I suppose an environment that has 300 agents and 2 private Security Gateway(Dynatrace SaaS).

Could you tell us whether some data loss occurs when 1 of 2 Security Gateway Stop?

If yes, how can we avoid that?

That can occur through a trouble or a planned maintenance.

Thanks

Hi Noah,

the Agents should send their data to the other Security Gateway if it's reachable for them. You can find documentation on this here:

Hi Franz,

Thank you for your response.

If 1 of 2 Security Gateway stopped, OneAgents connecting the stopped Security Gateway should find another Security Gateway.

And OneAgents check reachable Security Gateway every 5 minutes.

("5 minutes" is provided by support(JIRA) in other topics)

So, we suppose that data loss up to 5 minutes.

Could you tell me whether it is correct?

Best regards,

Hi Noah,

OneAgent caches the data for some time. I didn't find documentation on how long but this should cover these 5 minutes.

>network outages will not create gaps in data. all metrics will be updated after the connection is back online.
