I have a number of web servers that each serve a few web sites by host header. Each site is externally load balanced across the different servers. 

I'm trying to use NetworkService.Check(*) to monitor the individual sites on the individual servers. Does anyone know what the magic incantation is to supply a host header to NetworkService.Check(*) ?

Is there a way to bind an object tool (script) to the ports on a switch?
I'd like to be able to right-click a switch port and enable/disable that port on the switch.

Many nights at 2am, when the housekeeper runs, we get a few deadlocks on SQL Server.

SQL query failed (Query = "INSERT INTO idata_2301 (item_id,idata_timestamp,idata_value,raw_value) VALUES (1061,1591683195,'Ok','3')"): [Microsoft][SQL Server Native Client 11.0][SQL Server]Transaction (Process ID 57) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.

We also see some of the DELETE statements from the housekeeper failing for similar reasons: "SQL query failed (Query = "DELETE FROM idata_2637 WHERE (item_id=1817 AND idata_timestamp<1583907634) OR ..." [Microsoft][SQL Server Native Client 11.0][SQL Server]Transaction (Process ID 63) was deadlocked on lock | communication buffer resources with another process and has been chosen as the deadlock victim. Rerun the transaction.

This doesn't happen every night, and the number of deadlocks isn't the same every time, but it's often enough that it's waking people up at 2am.

Anyone have any thoughts on where to go to troubleshoot?

I can't find any documentation on it, but it looks like the agent polls ExternalParameters sequentially. Is this correct? If so, is there a way to run them simultaneously (say with some maximum degree of parallelism)?

I have a few external parameters that usually complete pretty quickly, but may sometimes take pretty long. It seems like they're pushing out some of the others....

Maybe I'm just dense and not seeing it, but is there a way to display the event parameters in the Event Monitor? I guess the same question goes for a node's EventLog.
Many thanks,

Peter

I'm trying to use Service.Check(*) to check a URL. Unfortunately, the URL I need to check is really long and looks like this:

https://hosta.mydomain.com/file1.aspx?KaB6rTg6%2fcIKlmbmN%40ecOi%2fjkr%407oXTOfLonrtxEolozX7HjHuvdXzfSZLXGSyM%2fz%2f88GXwVAXPhKIP893OYWC1N4zkKcFEoGnXlORpSV0GyA%40ljEZT3xDK72S46Y6luNEnz0lBYEqb8bzPEJ%40V28pJbIRpMLDp3uKPUnqit19t%40I5uY%40bZtcGI7NXZ5O81c8HDPmmxYci%40xpL7oAqLR9A%3d%3d

The URL above doesn't work and results in a "Cannot get current parameter value: Requested data collection item is not supported by agent" error.
If I shorten the URL slightly, the error goes away and it actually makes the call (but then obviously I have the wrong URL!)

https://hosta.mydomain.com/file1.aspx?KaB6rTg6%2fcIKlmbmN%40ecOi%2fjkr%407oXTOfLonrtxEolozX7HjHuvdXzfSZLXGSyM%2fz%2f88GXwVAXPhKIP893OYWC1N4zkKcFEoGnXlORpSV0GyA%40ljEZT3xDK72S46Y6luNEnz0lBYEqb8bzPEJ%40V28pJbIRpMLDp3uKPUnqit19t%40I5uY%40bZtcG

... works. If I add one more character, it stops working.

Is there a length limit to what's passed to Service.Check? If so, what's the limit?
Thanks!

Trying to run WMI.Query(/root/somenamespace, SELECT * FROM class WHERE name="value", property)
WQL needs the quotes, but by the time the query executes the quotes have been stripped. The same issue exists when trying to pass something in quotes to a ExternalParameter, or any parameter for that matter.

Is there a way to use quotes in parameters?

Going through the code, it seems the quotes are being removed in AgentGetParameterArg....

A few times I have made changes to the Windows template under \Templates\Operating Systems, only to find that it somehow automatically reverts overnight. Do the pre-built templates get recreated on a schedule somehow?

I feel dumb for asking this, but going to ask anyway: Using a standard out-of-the-box netxms installation on Windows, how do you install the WebApi?

I understand that the WebUI runs on Jetty so there should already be a server. How do we add the web api to this so we have something to point Grafana to?

Many thanks!

I might have missed it, but I'm looking for a way to display dashboards not unlike the alarm viewer application.

Our current setup has 8 dedicated monitors that display various dashboards (they're just full screen web pages). Is there anyway I can display netxms dashboards this way?

Windows 2008R2 (x64)

Although you can check the box in the installer (netxms-1.2.0-x64), it doesn't seem to install the webui. The separate webui install does create the WebUI folder and everything in it, but the service just hangs on "starting". The logs say that it can't find a jre, so I set JAVA_HOME to c:\netxms\bin\jre\bin and that makes it happier. However, it still won't start as "Local System", since it seems to search for temp folders. Manually running "java -war start.war" starts up the server properly in the console, but the gives the following error when you try to access the page:


Could not process server response:

Error: Operation "create" on target "w4" of type "null" failed:
No Adapter for type forms.widgets.Hyperlink
Properties:
parent = w12
style = NONE
bounds = 214,161,81,34
children =
tabIndex = 8

Uninstalled everything, reinstalled just the server. Installed tomcat 6 and deployed the nxmc war manually. Same error.

What am I missing???
Thanks!

I've seen this topic come up a few times: Could you please make a way to 'put a node into maintenance mode'? Scheduled would be super-awesome, but I'll gladly take manual. I really don't want this thing to wake me up at 3 in the morning when somebody is doing maintenance

From browsing through the 1.1.7 source, it looks like you have quite a bit of it in place with the 'disabled' status for a node. Just suspend all polling while the node is in maintenance mode. No data collected. No events generated. Etc. Just a single event that the node has changed status (into maintenance mode) and one when it's come out of maintenance mode.

Please? Pretty please?

Not sure if this is already possible through some workaround or not. If it is, I can't figure out how

All my servers have some form of out-of-band management card or connection (Dell BMC, Dell DRAC, HP ILO, Generic IPMI, etc). This connection has a separate IP address that doesn't show up anywhere. I'd like to monitor some things from that connection and propagate it as part of the device status.

Optimally, I'd like to just add DCIs and select the IP address of the management card. Come to think of it, you'd need more than just the IP address: you'd need almost all the communication settings. Perhaps this is actually a device as a child of another device?

It might be very useful to be able to set properties on a container, and have those propagate hierarchically down the tree. I'm thinking of things like SNMP community strings, agent secrets, status calculation method, etc. Preferably with an option to override on a per sub-container or sub-node basis.

When starting up the java console (1.1.7) on a remote machine, an error occurs saying 'Load MIB file on startup' has encountered a problem. Cannot load MIB file from server: URI has an authority component.

This doesn't occur when you start the console on the server.

What gives?

Hello,
I'm trying to pull the total number of hits on a web site through an agent. I think I've tried just about every variation, but I just can't make it work! This seems so simple....

Shouldn't it just be:
1) Add a new DCI to my server
2) Pick "Agent" as the source
3) Select "PDH.CounterValue(*)" as the parameter
4) Enter "\Web Service(<instancename>)\Total Method Requests" as the parameter


I feel like I'm missing something really simple....
Help? Please?
Thanks!

I've created two nodes and a cluster object. How do I move the nodes under the cluster? Or is the only option to recreate the nodes?

I have a variety of switches but most are monitored in similar ways. For instance, for all ports I'd like an event to occur when inbound or outbound errors occur. Or when utilization is above X.

You can obviously set this up as device based templates and apply, but is there a way to create interface based templates?

If I use two switches with HSRP, netxms detects the virtual IP address as a separate interface and moves it from switch to switch when the configuration gets re-polled and the active switch happens to have changed. Is this behavior by design?

When you walk the ifTable, only one interface shows.

Example config:
(switch1)
interface Vlan99
description VL99
ip address 10.0.99.2 255.255.255.0
ip verify unicast source reachable-via any allow-default
no ip redirects
no ip unreachables
load-interval 30
standby 99 ip 10.0.99.1
standby 99 timers 1 3
standby 99 priority 105
standby 99 preempt delay minimum 10
standby 99 authentication 99_1
standby 99 track GigabitEthernet2/1
end

(switch2)
interface Vlan99
description VL99
ip address 10.0.99.3 255.255.255.0
ip verify unicast source reachable-via any allow-default
no ip redirects
no ip unreachables
load-interval 30
standby 99 ip 10.0.99.1
standby 99 timers 1 3
standby 99 priority 100
standby 99 preempt delay minimum 10
standby 99 authentication 99_1
standby 99 track GigabitEthernet2/1
end

When switch1 has the HSRP address, netxms shows:

(switch1)
- VL99 (ifIndex=147,ipaddress=10.0.99.1)
- VL99:0 (ifIndex=147,ipaddress=10.0.99.2)

(switch2)
- VL99 (ifIndex=147,ipaddress=10.0.99.3)

Which 'instance of the interface' gets the :0 depends on who happened to get detected first.
Help?

Thanks!

Is there a way to make unconnected (but "admin up") interfaces not show as critical?
