Opened: Mar 02, 2021
Severity: 2-Critical

Symptoms

Sylog-ng uses the hostname (machine name) and truncates it starting at the first '.' (period). This results in hostnames that contain a period being logged incorrectly (for example, 'my.hostname' is logged as 'my' by syslog-ng). Additionally, hostnames are being truncated in bootmarker logs and the ltm, apm, apm, ipsec, saas, and fw_log that are sourced from TMM. Three sub-bugs BZ1076909, BZ1076921, BZ1080317 are created and BZ998649 is the base bug for tracking the above three issues.

Impact

Some logs that go directly to syslog-ng use a truncated hostname. Logs sourced from TMM uses truncated hostname.

Conditions

Hostname contains a period '.' (For example 'my.hostname').

Workaround

None.

Fix Information

None
