Title: Multiple DCIs Missing
Post by: radw on November 23, 2016, 12:28:20 AM
Hello, today checking my 2 NetXMS servers , I find that multiple DCIs stop to work, be discovered, appear without recent values, etc, even if the nodes are reachable.

Here are the performance graphs from both servers:

(https://s11.postimg.org/z60uqwzpr/Nov222016_P2.jpg) (https://postimg.org/image/z60uqwzpr/)


The same behavior appear from time to time , but I did nothing and later the DCIs and data appear again.


Is there a way to solve this issue for good ??


Regards.

Hello, yesterday I had the same issue, even entering nxdbmgr check on both servers.

For this, I rebooted both  servers, and then the DCIs reappeared (but not all at the same time), and up today I see almost all, but with their values missing for several days.

It's very disturbing this behavior.

Regards.

Hi,

what NetXMS version you are running? Are those DCIs collected from agents? If yes, are you using cache mode on agents?

Best regards,
Victor

Hello Victor, my answers:

1) Im running NETXMS 2.0.6 on Debian 8 (64bits):

:~$ nxdbmgr -v
NetXMS Database Manager Version 2.0.6 Build 8073 (UNKNOWN) (UNICODE)


~$ hostnamectl
   Static hostname: NETXMS-DEV
         Icon name: computer-vm
           Chassis: vm
        Machine ID: 0e2abe4338484ea5a790cd88bb82b757
           Boot ID: 3cfe0309bc734c1d82bf6f6f6732d42c
    Virtualization: vmware
  Operating System: Debian GNU/Linux 8 (jessie)
            Kernel: Linux 3.16.0-4-amd64

2) Are collected from SNMP agents (DCIs come from template, and have instantiated and transformation configuration)

3) On Template DCI,  the agent cache mode is "default", and "DefaultAgentCacheMode" have value 2 and restart=yes (I have not change any of these parameters).
