NetXMS Support Forum

From the log it looks like connection from server never gets to agent. Try to connect with telnet or nxget to this server from NetXMS server machine - you may get a bit more diagnostic. Also make sure that in node properties you have correct IP address.

Hi,

just fix it. Fix will be included into next release. You can also try this agent build with a patch: https://cloud.radensolutions.com/s/DWBNYGnGbSBMD59

Hi,

error message is like this because MS SQL driver uses ODBC API internally. Do you have MS SQL native client installed on the server?

Hi,

automatic alarm termination is defined by event processing policy. It should have been migrated along with other configuration. Try to check event processing policy rules related to both activation and termination events, and also check event log that termination event was generated.
What version you are using? Is it same version as before migration or you did both upgrade and migration?

I did a quick look at the code for reading firewall state, and it is indeed strange. Will dig deeper into it in next few days, as time permits.

Hi,

it looks that DCI data processing for some reason takes too long. Do you have any transformation scripts or script thresholds on those push DCIs?

Hi,

what is NetXMS version, and what are firmware versions on Mikrotiks? We did some fixes recently for handling incorrectly (in a non-standard way) reported LLDP data by some Mikrotik devices, so if version is relatively old upgrade may help. Otherwise I would like to look at SNMP walk results for .1.3.6.1.2.1.2.2, .1.0.8802.1.1.2.1.4.1.1, and .1.0.8802.1.1.2.1.3.7.1 for all involved devices.

Yes, currently network discovery code assumes that other zones are only fully reachable via proxy. I will think how to fix that.
Out of curiosity, what is the reason for creation of separate zone if everything within that zone is directly reachable from server?

Hi,

currently MODBUS/TCP is not supported, although we plan to add it.

Hi,

it should be possible with simple Java application (or maybe even nxshell script) that will receive data in NMEA format, extract coordinates, and update appropriate node object via NetXMS API. This can also be implemented as server module in C++.

Hi,

this could indicate bottleneck when objects are being saved to database. Try to enable parallel writes by increasing values of parameters ThreadPool.Syncer.BaseSize and ThreadPool.Syncer.MaxSize (I would recommend starting with 3 or 4 and see if there will be any difference). You may also increase value of SyncInterval to reduce number of writes. It also probably worth checking database performance.

Hi,

you can use script like this:

for(d : FindAllDCIs($node, null, "Signal - * Transceiver Receive Power Sensor"))
{
   value = GetDCIValue($node, d->id);
   if (vmin == null or vmin > value)
      vmin = value;
   if (vmax == null or vmax < value)
      vmax = value;
}
// Here vmin and vmax variables contains min and max values for matching DCIs

Hello,

yes, it's possible. I can take a look tomorrow at your server. Will send you PM with contact details.

Hi all!

We just published minor patch release for version 3.8. Only server and agent on FreeBSD 13 are affected. Changes since previous patch release:

- Fixed potential data loss in InfluxDB driver
- Fixed invalid memory access in NXSL VM when using expression variables
- Fixed interface counters access by agent on FreeBSD 13
- Fixed bug in CAS server access
- Fixed bug in report definition processing
- Fixed server deadlock during proxy load rebalancing
- Read system description before interface list during configuration poll
- Separate debug tag for SMTP sender

Hi,

you can create script DCI that will collect all necessary information into table. For example, create script in script library:

table = new Table();
table->addColumn("Node", DCI::STRING, "Node", true);
table->addColumn("Interface", DCI::STRING, "Interface", true);
table->addColumn("Speed", DCI::INT32, "Speed");

for(n : GetAllNodes())
{
   if (!n->isSNMP)
      continue;
   for(i : n->interfaces)
   {
    row = table->addRow();
    table->set(row, 0, n->name);
    table->set(row, 1, i->name);
    table->set(row, 2, i->speed);
   }
}

return table;


Then create table DCI on any node (I usually use node representing NetXMS server itself) with origin "Script". and set script name as parameter name. Value of this table DCI will contain list of all interfaces on all SNMP capable nodes with their speeds. By changing script you can add more columns and change conditions for inclusion as needed.

Victor
