i check the installation and i found that smtp channel is missing and the channel create before was set as dbtable
how can is possible? 
i have compilded the source as old server, missing some library on new server?

Andrea

Hi,

it's possible create a node and DCI imported from external source like influxdb? Since netxms still doesn't support the api to vcenter through SDK,  i want to configure influx and than import the metrics on netxms.

it's possible?

thanks

Andrea

Hi, i can't find an explanation about real function to the sample count for average value on DCI general tab.

For example, i need to monitor disk latency by windows perfcount. I know that windows has 1 second sample of this counter and i want to retrieve average value about 60 seconds. So i need to put 60 as value and than the agent collect every second the perfcount value and tell me the average of these 60 samples?

thank you for clarification.

Andrea

Hi,

Hi, i have a netxms installation on centos. I saw that with freetds i can run sql query directly from linux console. my goal is create a script on netxms server to run query on my mssql cluster.
i have already create a cluster node on netxms and i want to create a dci directly on cluster's object and not on cluster's node. it's possible?

thanks

Andrea

Hi, is possible to disable the short visualization for number like 1,000 instead of 1K?

thank you

Hi, i'm configuring node for my exchange server and i need to create a dci that is the average of this performance counter

\MSExchange ADAccess Domain Controllers(DC)\LDAP Search Time

for all my domain controllers.

can someone help me? give me an input to create a script?

thank you

Andrea

Hi, i have upgraded windows console from 2.2.1 to 2.2.3 and now i have this error on login

"org/betxms/base/GeoLocation"

i have upgraded also a server and webconsole and these work fine

thank you

Andrea

hi, i have installed agent on linux machine (centos 7) but on folcder  /usr/local/lib/netxms i can't find vmgr.nsm.

why? i need a special parameter during installation?

thank you

Andrea

Hi, i done some research on forum to understand how to retrieve a table from powershell's script and create a dci.

I found that dci's table doesn't support powershell and i can user "externalparameterprovider" on agent's file conf. But how?

In my case i need to retrieve a list of virtual machine from hyper-v cluster with powershell command Get-vm. My question is how can translate columns output from powershell script and traslate on table columns on dci's table?

thank you

Andrea

hi, i have installed netxm and i have added some cisco 3750 switchs. On interface down policy i have configured an email alarm.

The problem is that now i receive a lot of email when users shutdown their pc. Can i create (and how) a policy to monitor only some ports?

thanks

Andrea
