Hallo zusammen,
ich habe ein Problem mit meinem CentOS 8 Cacti-Server.
Dieser zeigt mir mehrere identische Geräte als Down an, obwohl diese online sind und produktiv laufen. Dies erkennt Cacti mittels SNMP und Ping auch richtig.
Die Fehlermeldung wird bei allen Geräten ausgegeben.
ERROR: HOST EVENT: Device is DOWN Message: Device responded to SNMP, UDP: Device is Down
Obwohl alle Geräte mittels SNMP und Ping erreichbar sind:
Hier noch die Liste wo ganz klar "Down" bei den Geräten angezeigt wird:
Das Seltsamste ist aber, sobald man sich als root per ssh im System einloggt, sind alle Geräte sofort erreichbar:
Wenn man sich von der Maschine ausloggt, brechen die Verbindung zu den Geräten ab und sie werden alle wieder als "Down" angezeigt.
Falls jemand das Problem kennt oder eine Idee hat bin ich für Ratschläge sehr dankbar.
Vielen Dank im Voraus für eure Hilfe.
Freundliche Grüße
Johannes

Hello guys,
I have a problem with my CentOS 8 Cacti-Server.
It shows me that some identical network devices are "down", but all of this machines running productive. Also Cacti gets all informations from SNMP and Ping correct.
This is the output error that cacti shows:
ERROR: HOST EVENT: Device is DOWN Message: Device responded to SNMP, UDP: Device is Down
All devices are successfully accessible with SNMP and Ping from Cacti:
Here is a list with all devices listed as "down":
The strangest thing is, that the devices are "up", if I connect me with the host machine via ssh:
After you log out from the host machine all machines are "down" again.
If somebody knows that problem or have an idea for a solution I'm very thankful for your messages.
Thanks for your help.
Kind regards
Johannes

Hey There sounds like some sort of network issue
Can you do a snmpwalk to these devices and a constant ping via the OS ?
at any time do you lose connectivity to the device via network?
