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

Actually we already decided that we have to move from libvirt to direct interaction with VMWare API (as we already did for XEN) - it's just question of available time and resources.

Best regards,
Victor

hi, with version 3.3 is possible use vmware api? if yes where i can find documentation?

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

thank you, it works.

cheers

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, i'm interested to this option because i want use netxms agent for windows event. Now i use graylog, but if it's possible pass all event's data to netxms i will use it instead graylog

Hi, thank you. I don't need disable this option on graph but i found the same voice for summary table.

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

thank you

Hi, thank you for reply, but i need to create a dci with average value of these DCI (i have 4 domain controllers)

\\MSExchange ADAccess Domain Controllers(DC1)\\LDAP Search Time
\\MSExchange ADAccess Domain Controllers(DC2)\\LDAP Search Time
\\MSExchange ADAccess Domain Controllers(DC3)\\LDAP Search Time
\\MSExchange ADAccess Domain Controllers(DC4)\\LDAP Search Time

I need to create a new dci with value that is average of these DCI's value.

I understood that i need to create a script and after link this script to a new DCI.

thank you

Andrea
