Re: [Observium] problem in graphics of more than 1000 devices

I think this written here more than 5 times.. why you still not done this?

Use RRDCACHED!

Hi Wilbert

I have a 4 Core with HT Xeon E3 1270 CPU @ 3.5Ghz 32GB Ram

Then 3 Raid 1 Arrays on Fast SSD Drives 1 for System, 1 for MySQL and 1 for RRD

The RRD one has to be on a Enterprise SSD which can handle big amounts of writes (several 10GB/5min) else it will get broken very fast. To reduce writes on the SSD I also recommend using rrdcached.

Matthias

What would be your recommendation the cpu, memory, hard disk since it is estimated to have up to 1500 devices?

 This is probably I/O related then.

 Your system isn't fast enough, you need either more CPU, more storage throughout or both.

     Hi,

     Derived from the first recommendation, update to ubuntu 18.04.01, also update to the latest version of Observium 18.9.9420, also update my version of php to 7.2 and after
     all that the behavior is the same.

         Yes, I/O can also be an issue.____

         This can be partially mitigated by using rrdcached.____

         You can also disable modules that you don't really need, like FDB collection.____

         Thanks,____

             Hi Wilbert,
             have a look at your I/O usage. Maybe your storage is too slow. I had
             similar problems and migrate from a VM to a physical server with SSDs.

                  hello can you please support me with the following situation I have,
                  I installed Obervium in a virtual machine with 8 Gb of RAM and 8
                  cores,
                  which have an Intel Xeon processor E5-1620 v3 at 3.50 Ghz, hard drive
                  of 200 GB, has installed a version of Ubuntu 16.04.5 with Observium
                  version CE17.9.0
                  when it had 30 devices added works well in terms of graphics, but
                  when we added more antennas in total 1085 at the time it has become
                  slow and also the graphics shows incomplete of any element, cpu,
                  memory, ports, etc, the devices aggregates are radios of ubiquiti and
                  mikrotik, I attach the images where it shows the commented of the
                  graphics


                  graph a month from a port




                  graph to 6 hours a port




                  the same situation occurs with the graphics of memory, processor,
                  memory or any ports of all devices

                  Wilbert.
