SNMP data delayed (not coming properly)- disconnected graphs

[zabbixfk]

Hi,

I am trying to monitor and collect data from some switches/routers/firewalls, using snmp v2.
What i observe is most of the time, data isn't hitting zabbix or its delayed.
Not sure what is causing this.
My current NPVS is 93, it is monitored via zabbix_proxy instance. and i see proxy holding more than 350+ items more than 10 mins.
The loss of data resulted in graphs with dots rather than straight line.

Is this something to do with proxy settings? I don't see any settings other than

StartSNMPTrapper=1

My proxy config file looks like this,

Server=zabbixmaster.internal.com
Hostname=zbx-proxy1
LogFile=/var/log/zabbix/zabbix_proxy.log
LogFileSize=150
DebugLevel=4
PidFile=/var/run/zabbix/zabbix_proxy.pid
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix
ProxyLocalBuffer=1
ProxyOfflineBuffer=2
ConfigFrequency=300
DataSenderFrequency=10
StartPollers=70
StartPollersUnreachable=15
StartTrappers=30
StartPingers=60
StartSNMPTrapper=1
ListenIP=192.168.0.2
CacheSize=1G
StartDBSyncers=25
HistoryCacheSize=1G
HistoryTextCacheSize=256M
Timeout=30
UnreachablePeriod=70
FpingLocation=/usr/sbin/fping
LogSlowQueries=300000

Below is the example. Here i am trying to get traffic details of an interface of a router. I am pulling every 6 mins (360sec) - but i see only limited entries instead of 10 for an hour.


Can anybody share how snmp data pull works ( i am doing snmp_get i guess) - as i have not able to get snmp_traps working

Can anybody share how snmp stuff works on zabbix.
Also please suggest if i need to tweak some settings.

PS: I am running zabbix with 2.0.6 version, and proxy server is also of same version.

Thanks

Can anybody share the idea/feedback/suggestion. The disconnection in graphs is increasing for SNMP based traffic monitoring, and i am stuck with no data

Hi,

Any pointers?

Hi,

First thing I see that your proxy configuration is far from optimal for your NVPS.
Please adjust the settings as many other performance tuning articles suggest. You can start with this for example.

Check Zabbix server and proxy logs to find any errors related to SNMP hosts you are monitoring.

Disconnected graphs for SNMP related monitoring items ( traffic )

Hi,

This is happening again. I am not sure what exactly should i be checking on the logs. SNMPget/walk gives me actual data and it works fine. Where as i see lot of disconnected graphs on zbx. What is the parameter requried to be adjusted for snmp poll in zabbix_proxy.conf - does increasing this lonely help?

Thanks
