Description

SLES-15(amd64/arm64) image family has been updated to point to SP7 recently. Every since SP7, the previously missing log label tid became available, for Apache 3P test.

See #1173: tid was missing before because SLES uses prefork MPM which does not use threads.

Why it is available now: SLES 15 SP7 is still using prefork. Looking at an example log:

[Tue Jul 08 22:32:33.900278 2025] [mpm_prefork:notice] [pid 9248:tid 9248] AH00163: Apache/2.4.62 (Linux/SUSE) OpenSSL/3.2.3 configured -- resuming normal operations

It is populating the tid field with pid - this is probably an Apache change that shows tid as pid when using prefork.

This should not have any impact, since:

1. this is an extra label for logs on SLES 15;
2. all other distro already have this label.
