Camunda cockpit elasticsearch plugin exception org.elasticsearch.discovery.MasterNotDiscoveredException

[said.h...@orange.com]

Hello,

 

I am trying to integrate camunda elasticsearch cockpit plugin in camunda 7.2 version.

My server is tomcat 7

I want use this search tool in my cockpit

 

I followed the steps described in the user github guide https://github.com/camunda/camunda-bpm-elasticsearch/blob/master/docs/userguide.md

 

When restarting tomcat server, I get this exception for two cases :

 

1/ In the first case, I don’t add the file elasticsearch.yml and I get this exception :

Hi,

I'm not familiar with this plugin and the maintainer is currently on vacation. But is your elasticsearch master

reachable from your node? Cause your root cause seems to be:

org.elasticsearch.discovery.MasterNotDiscoveredException: waited for [30s]

Cheers,

Sebastian

[Christian Lipphardt]

Hi Said,

You have to configure the connection to the Elasticsearch host.
I will add the configuration part to the documentation in the next few days.

You could create a local master node for testing purposes by adding following to your process engine configuration in bpm-platform.xml.
An 'elasticsearch.yml' is not needed.

<plugin>
  <class>org.camunda.bpm.elasticsearch.ElasticSearchHistoryPlugin</class>
  <properties>
    <property name="localNode">true</property>
    <property name="dataNode">true</property>
    <property name="clientNode">false</property>
  </properties>
</plugin>

Switching to a standalone elasticsearch installation is mandatory when running in production.

When you want to connect the cockpit plugin to the node, it should be enough to just add the elasticsearcg-cockpit-plugin.jar to the camunda-webapp.war.

Cheers
Christian

Hi Christian,

 

Thank you. It’s ok for me and i decided switching to a standalone elasticsearch installation in production.

 

Cheers,

Said.

Hi Christian -

I'm facing the same connection issue with ElasticSearch when running Camunda 7.3

How can I configure the elasticsearch plugin to connect to a Elastic Search standalone server?

Many thanks

isaac

[Daniel Meyer]

Hi Isaac,

I don't think that the elasticsearch plugin has been adjusted to support Camunda 7.3 yet.

Maybe Christian can provide some insight on this?

Regards,

Daniel

[isaa...@gmail.com]

Thanks Daniel

I was able to make it work with 7.3. Here are the steps I took to make it work:

Edit the file camunda-bpm-elasticsearch.json and put the following config:
{
"index": "camundabpm",
"type": "processinstance",
"indexingStrategy": "org.camunda.bpm.elasticsearch.index.ElasticSearchDefaultIndexStrategy",
"esHost": "localhost",
"esPort": "9300",
"esClusterName": "elasticsearch",
"transportClient": true,
"properties":
{ "es.script.disable_dynamic": false }
}
Do a mvn clean install
Next, you have to configure your elasticsearch.yml file, which is responsible for the elasticsearch node. Add the following lines to the file:
script.inline: on
script.indexed: on
script.groovy.sandbox.enabled: true
node.master: true
node.data: true
http.cors.enabled : true
http.cors.allow-origin : "*"
http.cors.allow-methods : OPTIONS, HEAD, GET, POST, PUT, DELETE
http.cors.allow-headers : X-Requested-With,X-Auth-Token,Content-Type, Content-Length

[Christian Lipphardt]

Hi Isaacsou,

You can also configure the elasticsearch plugin in the process engine configuration[1].

Just add your required properties to the properties section.

Besides that, the plugin isn't 7.3.0 ready and it has to be improved so you can configure which kind of history events from the engine are indexed and which should be ignored.

It currently only indexes evnets of type HistoricProcessInstanceEventEntity, HistoricActivitiyInstanceEventEntity, HistoricTaskInstanceEventEntity and HistoricVariableUpdateEventEntity. Any other events are ignored.

Cheers,

Christian

[isaa...@gmail.com]

Thank you so much Christian. That was valuable info.

I'm trying to display some of the Camunda events aggregated in Elastic Search into a Kibana dashboard, but I'm facing some issues in generating the reports due to the nested fields structure of the records, which Kibana seems to have difficulties supporting out of the box.

Will update this thread as I make any progress.

Best,
Isaac

Hi Christian,

Sorry to piggyback on this thread (never made a post before, I hope this is appropriate).

I've been trying to use this plugin on Jboss 7.2. However, I found many of the dependencies were broken. After I cleaned them up and stopped receiving file not found errors, I found myself stuck at this:
