Hi all,
This morning our Xymon system (Xymon 4.3.30-1.el8.terabithia on RHEL 8.6) was showing the main screens but when clicking on any status to see the data I was getting "no such host". I restarted Xymon and it all came back but all pages completely reloaded. We're missing RRD data for almost 24 hours. at 08:30 yesterday we started getting the following in xymongen.log which carried on every minute until I restarted it at 08:25 this morning.
2024-10-27 08:30:30.501407 xymond status-board not available, code 0 2024-10-27 08:30:30.501489 Failed to load current Xymon status, aborting page-update
There's nothing in xymonlaunch.log or xymonnet.log but at that time we got the following in xymond.log (actual servernames have been changed to "servername"
2024-10-27 08:30:13.048311 WARNING: Cannot open directory /etc/xymon/hosts.d 2024-10-27 08:30:13.048338 WARNING: Cannot open directory /etc/xymon/v9hosts.d 2024-10-27 08:30:13.048344 WARNING: Cannot open directory /etc/xymon/dynamicHosts.d 2024-10-27 08:30:13 Flushing filecache 2024-10-27 08:30:13 Rescanning host tree 2024-10-27 08:30:13 Sending dropstate (from xymond) with servername 2024-10-27 08:30:13 Sending dropstate (from xymond) with servername 2024-10-27 08:30:13 Sending dropstate (from xymond) with servername 2024-10-27 08:30:13 Sending dropstate (from xymond) with servername 2024-10-27 08:30:13 Sending dropstate (from xymond) with servername 2024-10-27 08:30:13 Sending dropstate (from xymond) with servername 2024-10-27 08:30:13 Sending dropstate (from xymond) with servername 2024-10-27 08:30:13 Sending dropstate (from xymond) with servername 2024-10-27 08:30:13 Sending dropstate (from xymond) with servername 2024-10-27 08:30:13 Sending dropstate (from xymond) with servername 2024-10-27 08:30:13 Sending dropstate (from xymond) with servername 2024-10-27 08:30:13 Sending dropstate (from xymond) with servername 2024-10-27 08:30:13 Sending dropstate (from xymond) with servername 2024-10-27 08:30:13 Sending dropstate (from xymond) with servername etc, etc .....
Then we repeatedly got
