NetXMS Forum

Thanks tomaskir.  Actually, I'm trying to write a Chef cookbook for netxms right now and was stuck without the init scripts.  Now I am good   Will share with the Chef supermarket and drop a note here once it is fully baked...

Problem was the I was trying to install "netxms-client" when I should have been installing "netxms-agent".  No idea what netxms-client is for, but it does install a few things (including netxms-base).  If it is just a remnant of something that isn't used, perhaps pulling it from the repo would prevent people like me (aka idiots) from using the wrong package...

Hello everyone.  I am trying to install netxms-client from the repo onto Ubuntu 14.04.  It installs without errors, but it doesn't create init scripts.  I've hunted around for anything named "nxa*" on the system; I'm not finding the init scripts and I'm not finding any default configuration file.

Any ideas where these went?

/etc/apt/sources.list.d/netxms.list:

Thanks!

Nevermind.  That actually did make it happy, I just needed to define the event on the server side.

Thank you!

Hey there.  Tried setting only MasterServers, didn't make any difference.

pace

nxagentd.conf from unit that has the logwatch on it:

Servers = xx.xx.xx.xx
ControlServers = xx.xx.xx.xx
MasterServers = xx.xx.xx.xx
ListenPort = 4700
LogFile = /var/log/netxms-agent.log
RequireEncryption = yes
EnabledCiphers = 1
MaxSessions = 32
SessionIdleTimeout = 60
FileStore = /var/nxagentd
TimeOut = 5
StartupDelay = 0
PlatformSuffix = dbg
EnableSubagentAutoload = yes
EnableProxy = no
EnableSNMPProxy = no
SubAgent = portcheck.nsm
SubAgent = netsvc.nsm
SubAgent = logwatch.nsm
# log watch parser definitions
*LOGWATCH
Parser = /etc/nxagentd.logwatch.zpool.xml

pace

I've got logwatch configured from what I can tell.  I am getting a notice in the agent log that the event I want is being created, but I never see it on the server.

Here's the logwatch xml:

<parser>
    <processAll>0</processAll>
    <file>/etc/nxagentd.logwatch.zpool</file>
    <rules>
        <rule>
            <match>DEGRADED</match>
            <event>10014</event>
        </rule>
        <rule>
            <match>ONLINE</match>
            <event>10015</event>
        </rule>
    </rules>
</parser>

Here's the event that is created in the agent log:

[23-Aug-2015 18:53:20.845] [DEBUG] SendTrap(): event_code=10014, event_name=(null), num_args=0, arg[0]="(null)" arg[1]="(null)" arg[2]="(null)"

Here are two more of the other event:

[23-Aug-2015 18:55:05.848] [DEBUG] SendTrap(): event_code=10015, event_name=(null), num_args=0, arg[0]="(null)" arg[1]="(null)" arg[2]="(null)"
[23-Aug-2015 18:55:05.848] [DEBUG] SendTrap(): event_code=10015, event_name=(null), num_args=0, arg[0]="(null)" arg[1]="(null)" arg[2]="(null)"

Nothing shows up on the NetXMS server under the node I'm monitoring or in the Event Log.

Any help much appreciated...

[EDITED to clarify NetXMS Server and Node difference]

@tomaskir said in Linux Memory Monitoring:

How are you getting the data - from SNMP or nxagent?

nxagent

Still having this problem.  Any solutions out there?

I'd like to be able to add a DCI to my host template that would cause the NetXMS server to check the host's service availability, for example SSH.  When I create a DCI in the template, the SSH test is run from the host rather than from the server.  I'd like to ensure that the NetXMS server can also access SSH.

Is this possible inside a host template?

Thanks!

So I've got my load balanced web servers.  I'd like to check the health of the load balanced site on the local web server, but I need to be able to send a host header because if I use the actual site name, it gets sent to the load balancer and therefore I don't know if my individual webserver is having an issue.  From what I can tell ServiceCheck.HTTP and HTTPS, while they have a configuration option for host header, they do not actually use it.

Do any of the agent tests support host headers?  I see Service.Check is based on curl -- can I send it a --headers somehow?

In 2.0M3 when I create a new Business Service Service Check Template it never seems to apply to anything that has already been created within or below the level where I create the template.  If I delete linked nodes that are at this level or below and add them back in after the template has been created then they get the expected Service Check applied to them.

I'm trying to monitor a website that is on a load balancer as part of a business service.  I'm not sure I'm approaching this the right way.  Should I add a "Service Check" -- if yes, what sort of script should I use to do the equivalent of a Service.Check?

Thanks for the help!
pace

I did as you recommended, but I still cannot create the object.  Additionally, I created a node named something specific ("test.test.com" for example).  I then deleted it.  Then I tried to recreate it and I get the "Object Exists" message.

pace

Cool.  I can confirm the 2.0M3 does it...

When I use Free or Available memory checks on Linux, it does not take into account the system cache.  This makes all my busy servers appear to have no memory to NetXMS because the systems start using all the free memory for file system caching.  Is there any way to take this into account?  Right now I'm checking for the use of swap to see if I'm really running out of memory -- I'd prefer not to do that and I would like to be able to check for free memory on my systems that have been intentionally configured without swap...

Thanks!

I'm trying to create a node that I will then use to monitor a network service.  This node is the head of a load balancer (I'm trying to make sure the site is running).  The problem is that I'm using Direct Server Response and the IP address of this load balancer head is in use on all the web servers (this is the appropriate configuration for DSR).  I'm getting the "object already exists" message because the IP address is attached to all the web servers and it isn't letting me create the node because of that.

What is the suggested remedy to this?

Thanks!

Hi there.  Whenever I restart my server, all of my file hash/security checks go on alert and I get a bazillion alerts, pages, emails.  These then clear as soon as the system is running the checks for a few goes.

Any suggestion on preventing all these notices when the server restarts?  Seems like the hash should be the same as before the server restart, but maybe it isn't getting permanently stored?

Additionally, all the UNSUPPORTED features that various agents all go on alert again on the restart.

Thanks for any help!
