Connectivity Problem on several hosts after update to OneAgent version 1.303

DanielS — Wed, 13 Nov 2024 14:41:05 GMT

Hi Community,

After upgrading to OA v1.303, I have several hosts and processes running on them with connectivity issues. Are there others with the same behavior?

I see that the latest release includes several updates related to the Infrastructure Observability | Hosts category. And some networking issues have been resolved:

Network module

Fixed calculation of the size of TCP data segment in case of TCP offloading. (OA-37005)
Fixed calculation of timeouts and time durations that could result in inflated retransmission metrics. (OA-35217)
Fixed a oneagentnetwork crash related to NIC state change from down to up. (OA-37724)

After reading the lasts updates to last version of OA deployed. I think the issues that have occurred now and not before on some hosts could be related to this update.

Hi,

The affected metric is TCP connection timeout which is causing the activation of a problem that apparently does not really exist. But on Windows platforms we have detected it in the TCP connection refused metric. This has been happening since yesterday after the update to 1.303.

Regards

Thank you very much Daniel, so far we have no feedback on our ticket. What we have done is to disable the anomaly detection for TCP connectivity since from the information we have had it is only a false positive.

We will be attentive to any news. Thank you very much. A couple of examples:

Support has informed us that this is happening to several customers and is under investigation.

Hi Ruben,

The problem has been quite strange, because it has not been massive, it occurs in some Hosts and in some clients, there are even similar hosts but it has not had the same behavior. In some cases it has been immediate after a restart, it may be that after the process restart the problem is activated.
In one Windows case the affected metric was TCP connection refused and it generated TCP connectivity type problems in IIS app pools.

I've seen in the Jira ticket that the fix went live with the newest OneAgent update, and the issue was resolved 😊

Hi Ruben,

At this point, we have not had the opportunity to update any customers or check a case. We hope to be able to check the fix as soon as possible. But this is good news. Thanks for the feedback.

Hi Macie,

At one of our customers we have already verified that 15 updated Linux hosts have fixed the problem.

Hey jpinto! OneAgent version 1.303.50+ has the fix for this issue and should be rolling out now to environments. If you're still not seeing it in your environment, please reach out via in-product assistance (live chat) or make a support ticket to have our teams push that version to your tenant(s). Thanks!

Linux or Windows? Our validation was done on Linux platforms only.
