[08:42:55] for what I see, linux 4.19.181-1 update is a regular bugfixing upgrade? https://metadata.ftp-master.debian.org/changelogs//main/l/linux-signed-amd64/linux-signed-amd64_4.19.181+1_changelog [09:17:02] jynus: yeah, it's the LTS kernel 4.19.181 (not really the latest and greatest, which would be 4.19.183) [09:18:39] that's ok, I am just happy it is not a "remote vuln fix" kind of update :-) [09:19:12] indeed! no, it's not :) [12:03:37] do we keep syslog/systemd logs longterm anywhere? [12:03:48] i'm interested in logs for a given machine from jan 21 [12:05:23] ah hah. `centrallog1001:/srv/syslog/` [12:05:57] yeah that's it! jan is definitely still there [12:07:00] kormat: they are in kibana too (syslog dashboard) you can filter by host and by absolute dates [12:07:13] volans: i've never dared to try to _use_ kibana [12:08:43] it isn't so bad, or maybe it is already too late for me and I've been assimilated [12:17:32] godog: the ui is impenetrable to me [12:17:44] e.g. i've managed to select the host and date range i want [12:17:54] but i cannot figure out how to search for messages containing 'mysqld' [12:18:09] add filter -> message -> ... there's no "contains" option [12:20:15] kormat: mhh my next try would be sth like *mysqld* in the top bar, however not all syslog messages are in kibana/logstash [12:21:06] 'no results found' https://logstash.wikimedia.org/goto/dc94071c79add1897c0443f20fd0f0c4 [12:21:29] oh, great. it mangled my time window [12:21:43] yeah I don't think we have mysqld logs in there [12:22:38] godog: so we send syslog to ELK, but _filter out some services_? [12:22:53] (because on debian /var/log/syslog contains the mysqld messages) [12:23:35] the other way around, only some "program"s from the syslog firehose are sent to ELK [12:23:49] centrallog has the full firehose though [12:24:43] where is this filtering done? [12:25:49] by the host's rsyslog via 'lookup_table_output.json' [12:29:19] FWIW the "syslog experience" now is obviously far from ideal, there's sort of a tracking task at https://phabricator.wikimedia.org/T254605 [12:42:02] godog: thanks for the info 👍 [13:53:28] one more cloud-specific patch, https://gerrit.wikimedia.org/r/675802 . this one affects non-deployment-prep servers but I think removing that profile is safe since it doesn't remove the LVM volume from old VMs [14:48:08] in addition to that, got a few beta-only hiera patches: https://gerrit.wikimedia.org/r/c/operations/puppet/+/675807 https://gerrit.wikimedia.org/r/c/operations/puppet/+/675814 and https://gerrit.wikimedia.org/r/c/operations/puppet/+/675815 [14:51:18] kormat, Andrew B. proposed a patch recently and this were the current blockers: https://gerrit.wikimedia.org/r/c/operations/puppet/+/664678/1#message-5ec6d5c03f25b5e3b383d5e79515bb3f23dc80c4 [14:52:04] jynus: 👍 [14:52:48] not sure what is the best way to overcome them a) fixing mariadb or b) creating a private logstash, B seems more feasable in the short term 0:-)
