Since the Squid-Cache project doesn't maintain the SNMP part of it as far as

Doesn't it?
I mean, some data are already avilable via SNMP.
If there are gauges and counters in squid and they are available via SNMP,
we can expect them to be correct, am I right?
is it that they are in squid but not available via SNMP?
Using extended SNMPD ie in /etc/snmp/snmpd.conf
extend squid_x_stats /bin/bash /usr/local/bin/squid_x_stats.sh
while the binary itself probably will be a single command/script that will
have symlinks to itself with a different name (like what busybox provides
binaries).
With a set of these commands it would be possible to monitor squid via the
linux SNMPD and the backend would be a script.
To overcome a DOS from the SNMP side I can build a layer of caching in
files.
It would not be like the current squid SNMP tree of-course but as long the
data is there it can be used in any system that supports it.
I have used nagios/cacti/others to create graphs based on this concept.
I am currently working on the PHP re-testing project and it seems that PHP
7.4 is not exploding it's memory and crashes compared to older versions.
I still need a more stressed system to test the scripts.
I have created the next scripts for now:
* Fake helper
* Session helper based on Redis
* Session helper based on FS in /var/spool/squid/session_helper_fs
