Joshua Boniface 612045b8b3 Restore original rsyslog-rotate script 
Direct call doesn't work because of how arguments are passed to
postrotate.
 2023-09-01 15:42:29 -04:00
Joshua Boniface 5cd9566163 Explicitly use systemctl in logrotate 
For some reason (Debian bug?) the default rsyslog-rotate script was not
properly rotating rsyslog logfiles. Instead, explicitly call systemctl
kill -s HUP for this, using a full path.

Also update to newer htoprc layout from BLSE.

Joshua Boniface 5a48ec4d79 Ensure CPU tuning is only applied on Debian 11+ 2023-09-01 15:42:29 -04:00
Joshua Boniface 07d75573d6 Add updated tuning configuration 
Uses a much nicer CPU tuning configuration, leveraging systemd's
AllowedCPUs and CPUAffinity options within a set of slices (some
default, some custom).

Configuration is also greatly simplified versus the previous
implementation, simply asking for a number of CPUS for both the system
and OSDs, and calculating everything else that is required.

Also switches (back) to the v2 unified cgroup hierarchy by default as
required by the systemd AllowedCPUs directive.

Joshua Boniface 30ddeb0fee Update MOTD automatically on boot 
The cron every minute was pointlessly excessive considering this doesn't
actually change minute-to-minute.

Joshua Boniface 86026de8ef Adjust colour scheme of MOTD 2023-09-01 15:42:29 -04:00
Joshua Boniface 8e1d005d43 Obtain more information for MOTD header 
Add model and serial numbers to the vendor, and put this on its own
line. Also use BASH for proper syntax formatting. Reformat the header to
be a more compact format.

Joshua Boniface e8fe165e00 Further optimize ownership agent output 2023-09-01 15:42:28 -04:00
Joshua Boniface cbea6e284c Make ownership check consistent with cmk-agent 2.1 
The new CheckMK agent uses UID 998 (dynamic) for itself. This causes
ownership problems with the old logic of this check. Move instead to a
range, where the UIDs from 200-599 are reserved for administrators, and
check for this range explicitly. Also eliminates the exceptions for ceph
and 2000 from previous iterations.

Joshua Boniface 9e20e47903 Update freshness checks 2023-09-01 15:42:28 -04:00
Joshua Boniface d47d320bb3 Replace freshness and kernel_version checks 
Use an updated plugin from BLSE that uses needrestart instead of manual
parsing of these elements.

Joshua Boniface 95b47f8b09 Fix a few more extraneous splits 
Just use this_node if applicable, or the raw node.hostname.
 2023-09-01 15:42:28 -04:00
Joshua Boniface d24cb8a8ef Unify and standardize inventory_hostname 
This was causing some confusing conflicts, so create a new fact called
"this_node" which is inventory_hostname.split('.')[0], i.e. the short
name, and use that everywhere instead of an FQDN or true inventory
hostname.

Joshua Boniface 056c325486 Add option for setting CPU governor 
Allows the administrator to set a CPU frequency governor if they need
to, though the default of ondemand is usually sufficient.

Joshua Boniface ddecb94348 Disable unified cgroup heirarchy on kernel cmdline 
This is required on Debian 11 to use the cset tool, since the newer
systemd implementation of a unified cgroup hierarchy is not compatible
with the cset tool.
