Thanks for the tip, this indeed solved the problem. Egert

I´ve installed NetXMS 4.2.395, webui 4.2.398, Grafana 9.3.1. and the NetXMS Plugin 1.2.3 on the same Windows Server 2019. I never used Grafana before. Now I tried to connect to NetXMS with Grafana but get an error "HTTP error Gone" The api is shown in the Browser correctly, The User is memebr of NetXMS admin Group Could someone help me here?

Thanks Alex.

Hi, gkaudewitz. First I appreciate your time to reply my follow-up message. Second, I am going to follow your comments. Thanks. My best Jose

Overnight we had an object that suddenly started flooding NetXMS with severity changes due to what I can only describe as Event flapping. Specifically...   12/13 21:00 - Device goes unreachable due to network failure. 12/13 21:01 - Device returns to normal. 12/13 22:04 - Device goes unreachable again 12/13 22:14 - Device back up and goes normal. 12/13 22:22 - Object Severity starts bouncing from CRITICAL to NORMAL multiple times per second; Event column shows flapping between SYS_NODE_CRITICAL and SYS_NODE_UNKNOWN;  20+ times per second. A network unreachable alert is logged at this time. 12/13 22:22 to 12/14 08:47 - Flapping continues unabated; two more network unreachable entries are logged at 22:28 and 22:54; none after that.   12/14 08:47 - Placed in Maintenance Mode. 12/14 09:20 - Taken out of Maintenance Mode.  No further bouncing. We confirmed through other sources there were no issues with the device or the connection to it. We've seen this happen a couple of times in the past, but the issue occurs so infrequently that this is the first time we've had a chance to look into it.  Forum searching turns up nothing related to this that is useful.  The closest we could find was this thread https://www.netxms.org/forum/general-support/too-much-alarm/ .  But the cause noted there did not apply here. So we're at a loss as to what would have caused this flood of Event log entries.  Any pointers on where to look for further clues would be helpful.

Hi, If you have custom attribute with name: "Region" and you want filter all nodes where custom attribute value is "Latvia" your request URL should look like: API_BASE/objects?@Region=Latvia

What changes have you performed prior for this to happen? Did you upgrade NetXMS? From what version to what version (exactly)?

In 4.2 support for TCP proxying was added into agent and desktop management client (and was not yet documented) Agent should have EnableTCPProxy=yes in it's config In management client it's done via Object Tools, there's "Setup TCP tunnel..." checkbox. There are two macros - ${local-address} and ${local-port} which are replaced by actual local IP and port So Local Command object tool with command mstsc /v:${local-address}:${local-port} should work for RDP

What exactly version of NetXMS do you have? Could it be that your NetXMS got upgraded recently?

I'm sorry for late reply, but after further verifications it turns out that juniper vlans (all junipers, VC and the single one) are wrongly recognized by netxms v4.2.433 I don't know if denpends on the patch created for this thread and wrong vlans are too random for me to identify a specific pattern of the beahviour. For Virtual Chassis i confirm the patch resolve the empty vlan bug for interface aggregations, but single interfaces have sometimes a lot of vlans (like the trunk) when it should be only one, other times have wrong vlanid or empty vlans .

If you have that node under some other container or template, you can remove it from cluster and then you can add it to another cluster (all done from cluster context menu). By the way, how many clusters do you have in your system (just to understand the scale how people use clusters)

Something like this may happen right after server start, if you are taking values from a DCI that has quite frequent collection interval. In this case server is not getting last collected value from database, but awaits it from agent. You can check if GetDCIRawValue returns null and handle this situation in the script.

Hi Victor, Thank you very much for your attention. I believe it will help other users as well. When it's ok, I'll test and come back here.

Hi!  I am having trouble getting an image of my network map, its lagging so bad, that even netxms console client itself is crashing and going into Not responding state for minutes, I have to wait 5 minutes to make a click or move anything, could be performance problem be on the server side or my PC isnt just strong enough to render the picture. And when i finally get to save an .png image, it won't do it. I can see from my PC that file was made but, its 0 KB and has different name or has been moved? Is there possibility to save it from command line itself?    Any tips?

Hi, the problem is on a nexus 93240 but not on nexus 93360 with similar configuration  ... very strange. Fred

Hi, You have to build those two libraries yourself from their sources. Best regards, Victor

For version 4.3 we have also added new metric File.Type, which returns 0 if file does not exist, 1 if it is a directory, 2 if it is a device, and 3 if it is a regular file. Best regards, Victor

Hi! most likely server does not have certificate. If this is the case than you can safely ignore this error, or delete problematic DCI. Best regards, Victor

ok so I was able to to achieve what I wanted with the following its hacky  but if works. How do I go about terminating this alarm ? I want to terminate the alarm as soon as the time expires. ts = ReadPersistentStorage("ts_".$node->name); if(ts == NULL){ /* create initial timestamp and event*/ WritePersistentStorage("ts_".$node->name,$event->timestamp); WritePersistentStorage($node->name,1); return; } /* if within time range of 10min check storage */ if (time() - ts <=600){   events = ReadPersistentStorage($node->name); WritePersistentStorage($node->name,events+1); if (events!=NULL ){ if (events >=5){ return true; } } }else{ /* if time is over 10min reset storage values for timestamp and event*/ WritePersistentStorage($node->name, NULL); WritePersistentStorage("ts_".$node->name, NULL); }

Dears, Here my stats results,     netxmsd: show stats     Objects............: 75948     Monitored nodes....: 1034     Collectible DCIs...: 1822     Active alarms......: 3337 And here are my changes of server configuration values     ThreadPool.Syncer.BaseSize: 10     Events.Processor.PoolSize: 10     ThreadPool.Syncer.MaxSize: 10     DBWriter.DataQueues: 8     ThreadPool.DataCollector.BaseSize: 30     ThreadPool.Poller.BaseSize: 200     DBConnectionPool.BaseSize: 15     DBConnectionPool.MaxSize: 100     ThreadPool.Agent.BaseSize: 10     ThreadPool.Main.BaseSize: 15 I'm facing multiple issues: I found a lot of DCI readings are errors when I open last values tab (they change from time to time). I have nearly 90 network maps each map represents a device image with dci readings on it, many times when I open any one of them, I got load image error. Some of my SNMP devices lose their interfaces or I found only one- interface although when I run poll full configuration it returns all its interfaces again. I use web client, after a long time without login, when I try to login it gives me request time out, so I restart the server.
