Rrdcached question

I just have a question that hopefully one of the kind folks here can answer. I have the latest Librenms package installed on Ubuntu 22.10. It is running fine, and I do not seem to have any issues. I was thinking of enabling “Fast Ping”. The documentation refers to rrdcahed by stating “If you are using” and “If Applicable”. So, my question is, do I need rrdcached to use Fast Ping? The documentation seems to make the assumption it is installed. So, I am confused as to whether I need it or not. I believe I am just using the standard cron poller rather than distributed.


Component Version
LibreNMS 23.2.0-46-gd508d2d6f (2023-03-30T15:04:06-04:00)
DB Schema 2023_03_14_130653_migrate_empty_user_funcs_to_null (249)
PHP 8.1.7-1ubuntu3.3
Python 3.10.7
Database MariaDB 10.6.12-MariaDB-0ubuntu0.22.10.1
RRDTool 1.7.2
SNMP 5.9.3

I fixed this.


Would you mind posting your solution?

I found that it is not required to have rrdcached installed. It is optional. I set things up according to the documentation ignoring the parts about rrdcached, and then tested and verified that pings were happening at the proper time.
