Recently I ran into an issue where a librenms install was taking up a crazy amount of disk space. This was tracked down to the syslog.ibd file . Even thought I had set my options to be less than 10 days per this link https://docs.librenms.org/Support/Cleanup-options/ I still was having a huge file.
Here is what I did to fix it. My root partition was too full to start MariaDB. I went into var and cleaned out enough log files to make space to start MariaDB. The following are tee commands I ran on CentOS 7 to fix it.

DELETE FROM syslog WHERE timestamp < '2021-1-28 08:00:00';

Another water tower install earlier this year for a client. To critique our own work the cables were moved under the mounts after these pictures were taken. this was done to minimize damage to the cables.
The following are leasing companies that I have worked with on securing vertical real-estate over the years. This is not a total list of tower companies. If you provide co-location services to Wireless ISPs and want to be included please reach out to me. Donations motivate me to update these lists. Ones with a Star next to them are WISP friendly from our dealings.
