NetXMS Support Forum

Agent is installed on windows 10 machine. This bug has been around for as long as i have been using netxms (so oldest agent i tryed should be 2.2.16) and currently i am using 3.3.314.

Maybe its somekinde timeout? Because upgrade proccess takes longer when machine is under full load ?

Thanks for the reply, i managed to make litle powershell script for task at hand.

Hello

When upgrading agents with NetXms, i get failed update when target machine is @ 100% cpu usage, even when trying multiple times. When i pause the app that is causing high load then agent upgrade works fine. What could cause this ?

Hello

Is it possible to parse webpage output into dci result?

for example if webpage returned data like:{
  "cluster_name" : "test",
  "status" : "green",
  "timed_out" : false,
  "number_of_nodes" : 2,
  "number_of_data_nodes" : 2,
  "active_primary_shards" : 0,
  "active_shards" : 0,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 0,
  "delayed_unassigned_shards" : 0,
  "number_of_pending_tasks" : 0,
  "number_of_in_flight_fetch" : 0,
  "task_max_waiting_in_queue_millis" : 0,
  "active_shards_percent_as_number" : 100.0
}

how would i get "status = good" out of it ?

Hello

Would it be possible to implement layers to World Map? So different layers could show different nodes. Also would it be possible to add links between nodes and show them on world map?

Script has error on line 4. maybe null value ?

Hello,

when using MsSql database, does the upgrade also create new tables that result double the usage ?

Thanks, that worked.

Thanks for the tip. Gave it a try:

From ps fox i got:

  922 ?        Ssl   14:57 /usr/share/kibana/bin/../node/bin/node /usr/share/kibana/bin/../src/cli -c /etc/kibana/kibana.yml
3454 ?        SNsl  14:49 /usr/bin/java -Xms1g -Xmx1g -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -Djava.awt.headless=true -Dfile.
2462 ?        SLsl  49:45 /usr/share/elasticsearch/jdk/bin/java -Des.networkaddress.cache.ttl=60 -Des.networkaddress.cache.negative.ttl=10 -XX:+AlwaysPreTouch -Xss1m -Djava.awt.headle


Then i played litle bit with regex tester:

Match string and regex = \/kibana\/

/usr/share/kibana/bin/../node/bin/node /usr/share/kibana/bin/../src/cli -c /etc/kibana/kibana.yml

But in NetXms i get 0 results no matter what formating i use in dci:
Process.CountEx("/kibana/", "\/kibana\/")

For NetXms i got it working, but looking from "top" the ELK processes are all java, only different user.

  PID USER      PR  NI    VIRT    RES    SHR S %CPU %MEM     TIME+ COMMAND
2462 elastic+  20   0 3379664 1.457g 173544 S  8.3 75.0  23:30.87 java
3454 logstash  39  19 3318852 222712  12784 S  1.3 10.9   4:06.48 java
  922 kibana    20   0 1701224  62008   6984 S  0.7  3.0   4:01.10 node

Looks intresting il give it a try. But any hints on original question for simple service monitoring ?

Hello

Linux(ubuntu server edition) beginner here, In short i wanted to test ELK Stack and Netxms to monitor its state. Got elk running but i cant figure it out, how to monitor linux "services".

i start them with commands:

sudo systemctl start nxagentd.service
sudo systemctl start elasticsearch.service
sudo systemctl start kibana.service
sudo systemctl start logstash.service
sudo service keepalived start

in NetXms i tryed adding: DCI System.ProcessCount("nxagentd.service") but it returns as unsupported.

Any hints?

Thanks for clarification.

For some reason i thought that multiple nodes with same ip cant be added, but if added as 0.0.0.0 first that did the trick. What exactly does "This is address of remote management node" checkbox do under the hood ?

Egert

Thanks for fast fix
