NetXMS Support Forum

Many many thanks, bit smarter about NetXMS again.

Hello

Is there any good ways to update ~200 agent configs to support file manager subagent or is the only way to one by one update them ?

Egert

That would be very helpful.

Hello

Would it be possible to implement time frame selection in node-performance tab, but one that changes all metric displays at once?

Egert

Got that part working, any good suggestions how to implement something like that:

example:
packet size 1500+ pings = good
less then 1500 pings but bigger packet not = bad
no response = external network down

sometimes network provider network wount pass packet size over for example 1000 and that kills vpn tunnel.

Hello

Question when i am monitoring router with local network address, is it possible to monitor external address also within same node or do i need to create seperate node ? Also how can i check if large packet ping is working ?

Hello

It means that ODBC driver is missing, need to install it seperately. Some info: https://stackoverflow.com/questions/17115632/microsoftodbc-driver-manager-data-source-name-not-found-and-no-default-drive

Indeed the template was missing, got it fixed. Database is MS Sql and data disk is 1tb ssd in raid 1, disk write,read and idle times are basicly non existing so drive is keeping up nicely.

I set ThreadPool.Syncer.BaseSize and ThreadPool.Syncer.MaxSize to 4 will let it run for a bit.

Any good metrics to monitor to indicate Netxms performance issues ?

Thanks, got it working.

yesh, big numbers solution worked, sometimes it the simple things that work but one does not think about them.

May i also ask what script would loop throught all dcis in given node, so i could retrive min and max values for last week and set custom attributes if not already set?

dci examples

Signal - Ethernet1/1 Lane 1 Transceiver Receive Power Sensor
Signal - Ethernet1/1 Lane 1 Transceiver Transmit Power Sensor
Signal - Ethernet1/2 Lane 1 Transceiver Receive Power Sensor
Signal - Ethernet1/2 Lane 1 Transceiver Transmit Power Sensor

Thanks for the reply, i tried option nr2. When custom attribute is defined for min and max value and two thresholds set for upper and lower limit it works good. But on instance where custom attribute is not set it will generate alert on default value. How can i not set default value. So only alert if custom instance attribute is defined.

so far i have tried:
%{signal_min:0}
%{signal_min:NULL}
%{signal_min:}
%{signal_min}

Custom atribute:
signal_min::Ethernet1/17 Lane 1 Transceiver Transmit Power Sensor

Hello

My current setup has grown litle bit and i have noticed errors stating "Syncer Thread not responding" they come and go. Am i hitting the server limit or is there some tuning to be done ?

It should be mostly default values. Where can i start investigating what is bottlenecking ?

Hello

Does anyone have good suggestions how to monitor SFP module TX/RX values. Well i am collecting them but what would be good strategy to alert on "bad" value? For example i have 48 port optical switch, almost all SFP modules report different values and there is no good threshold value that suits all. Idealy i would like to set alerting based on signal level that was observed when link was established. But with auto discovery its impossible to set those values.

I am interested in detecting events when signal is degrading over time, for example if signal has changed alot over 2-3 days for example.

Hello

Has someone used Peplink lte router and monitored it with NetXMS? I am interested in retriving the GPS cordinates from the router. I searched snmp output for cordinates but it seems not to be available. Option #2 would be using builtin router function called gps forwarding but not sure if NetXMS can receive them?

Possible settings:
Server: ip,port,protocol,report interval
GPS Report format: NMEA, TAIP
NMEA Sentence type: GPRMC,GPGGA,GPVTG,GPGSA,GPGSV
TAIP Sentence type: PV,CP
