[Observium] Why sometime graph are missing on the dashboard ?

12 Oct 2020


      Dear All,
I've sometimes found that some server graph RAM / CPU / Traffic is missing
on the dashboard. So, I can't view the graph at that time.
But when I check on the next time, that graph shows again.
What caused it and how to solve it ?
My detail specs:
Device Monitor: 400++ VM (various OS Linux & Windows)
CPU: 8 Core
RAM: 12 GB ( Use Ramdisk )
Storage: 500 GB on SSD
Observium 20.1.10233 (20th January 2020)
OS Linux 3.10.0-514.el7.x86_64 [amd64] (CentOS 7)
Apache 2.4.6 (CentOS) OpenSSL/1.0.1e-fips PHP/7.0.19
PHP 7.0.19 (OPcache: ENABLED)
Python 2.7.5
MySQL 5.5.52-MariaDB (extension: mysqli 5.5.52-MariaDB)
Demikian yang dapat kami sampaikan, terimakasih.
