ldms_core home page
The new alert system in version 8.8 can get stacked up on low-performance cores, and it doesn't purge records unless you tell it to. ldms_core will now check that queue and purge records older than X days. There's also an email test button in the setup window, so you can make sure you've got email right.
I've also updated the manual.
Kinda unrelated, but what is the purpose of checking your version at the site? I have always gotten this and just plan ignored it cause the things works well otherwise:
