Description ==================================================== Add timestamp option to virtlogd.conf When timestamp=1, let virtlogd prepend timestamps at start of line, i.e. append timestamp after '\n' character. This can be a useful debugging feature to help us see timestamp along with commands/operations run inside the VM Previous discussion link : https://listman.redhat.com/archives/libvir-list/2023-August/241562.html Test ===================================================== Set timestamp = 1 in virtlogd.conf systemctl restart libvirtd If VM's xml has something like : <devices> ... <console type='pty'> <log file='/var/log/libvirt/vm-serial0.log' append='on'/> <target type='serial' port='0'/> </console> </devices> Sample Output of /var/log/libvirt/vm-serial0.log: ... 2024-02-22 09:36:33.898+0000 Last login: Sat Feb 10 10:48:00 on ttyS0^M 2024-02-22 09:36:33.953+0000 [root@localhost ~]# ll^H^[[K^H^[[K^M 2024-02-22 09:36:36.930+0000 [root@localhost ~]# ls^M 2024-02-22 09:36:38.224+0000 anaconda-ks.cfg original-ks.cfg test.py tmp x.txt^M 2024-02-22 09:36:38.226+0000 [root@localhost ~]# ^M 2024-02-22 09:36:40.062+0000 [root@localhost ~]# l^H^[[Kyo^M 2024-02-22 09:36:44.292+0000 -bash: yo: command not found^M 2024-02-22 09:36:44.293+0000 [root@localhost ~]# Shaleen Bathla (4): logging: virtlogd: Add option to append timestamp to domain logs util: virrotatingfile: Introduce virRotatingFileWriterAppendTimestamp util: virrotatingfile: virtlogd timestamp appending logic tests: virrotatingfiletest: update virRotatingFileWriterAppend src/logging/log_daemon_config.c | 3 ++ src/logging/log_daemon_config.h | 1 + src/logging/log_handler.c | 10 +++-- src/logging/test_virtlogd.aug.in | 1 + src/logging/virtlogd.aug | 1 + src/logging/virtlogd.conf | 4 ++ src/util/virrotatingfile.c | 69 +++++++++++++++++++++++++++++++- src/util/virrotatingfile.h | 3 +- tests/virrotatingfiletest.c | 34 ++++++++-------- 9 files changed, 104 insertions(+), 22 deletions(-) -- 2.39.3 _______________________________________________ Devel mailing list -- devel@xxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxx
