Perl solution:
perl -F'/\|/' -ne '$id = $F[0] if $F[3] =~ /- 44$/;
print if $F[0] eq $id && $F[3] =~ /Logged In|Processed Bill/;
' -- file.txt
-n reads the input line by line
-F splits each input line on the given regex into the @F array
if $F[3], i.e. the fourth column, matches - 44, the first column is stored ...

To enable OpenLDAP debugs, you would want to add the following to your slapd.conf
loglevel <level> (eg: stats)
If you do not use slapd.conf, you may then pass that option to the slapd service. In debian/ubuntu, you would find some /etc/default/slapd file, you may update its SLAPD_OPTIONS:
$ grep SLAPD_OPTIONS /etc/default/slapd
SLAPD_OPTIONS="-s 256"...

You can use hardcopy -h command to save the contents of the current scroll buffer
to a file. As described in man screen:
hardcopy [-h] [file]
Writes out the currently displayed image to the file file, or,
if no filename is specified, to hardcopy.n in the default
directory, where n is the number of the current window. This
either appends or ...

One way to do it is to use copy mode to copy the entire scrollback history, then dump it into a file. (There is likely a better way.)
With default keybindings, this would be something like:
Ctrl-A to send screen a command
[ to enter copy mode
g to go to the top
Space bar to mark the beginning of the scrollback buffer (where you are) as the start of the ...

ls’s -u option can be used to list files with their last access time (instead of the default last modification time):
ls -lu
Since you’re trying to examine large amounts of files, the recursive option could be useful:
ls -luR
You can also list all files accessed in the last two days using find:
find . -atime -2
and multiple specifiers can be combined ...

It looks like a known bug on nouveau driver (if i remember well, this is the opensource driver for NVidia graphic cards).
Source: https://bugs.freedesktop.org/show_bug.cgi?id=99900
To fix this you can:
Use logrotate or a cron job to flush logs passed a given size.
or
Tweak your syslog configuration to avoid logging this.
or
Totally disable syslog (...

It takes some careful shell quoting, but you could use the scriptable editor ed for this:
printf '%s\n' "/foo/ka" "??" "'a,.w "'!less' q | ed -s file
This sends four commands to ed:
/foo/ka -- searches (from the beginning of the file) for the pattern foo; at that first match, set a mark named a.
?? -- repeat the search, but going backwards, wrapping ...

/var/log is a directory and cannot be opened by cat. Perhaps you actually wanted to open one of the files inside /var/log/?

These commands are, indeed, part of the sysstat package. It's intended for performance monitoring; and specifically, sar is the system activity report:
a Unix System V-derived system monitor command used to report on various system loads, including CPU activity, memory/paging, interrupts, device load, network and swap space utilization. Sar uses /proc ...

You could do something stateful like
/first-pattern/ {print; p = 0} /second-pattern/ {p = 1} p
Ex.
$ awk '/^criteria/ {print; p = 0} /(Old|New) run:/ {p = 1} p' file.log
criteria (NO-NO) data/speed/profile_1
Old run: exit speed=22.5
Old run: ramp speed=15.2
New run: exit speed=28.2
New run: ramp speed=19.3
criteria (NO-NO) ...

Ok, your logrotate is failing because of missing log files. When you use logrotate -d you are getting verbose debug output but logrotate does not do anything. If you first do
logrotate -v logrotate-message -f
instead the force option, combined with verbose output will show you the operation of -f flag, which per man logrotate will create missing log files ...
