Hi,

I have an issue when try to connect to external elasticsearch 6.8 with DMA, I’m using this DBConfiguration.xml config.

<?xml version=”1.0″?>
<DataBases xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance” xmlns:xsd=”http://www.w3.org/2001/XMLSchema” xmlns=”http://www.skyline.be/config/db”>
<DataBase active=”true” local=”true” type=”Elasticsearch”>
<ConnectString/>
<DBServer>35.175.118.112</DBServer>
<DSN/>
<DB></DB>
<UID>elastic</UID>
<PWD>changeme</PWD>
</DataBase>
</DataBases>

I get this error when restart DMA.

Hi Jose,

I was wondering, did you check first if you are able to query the Elasticsearch node from the server where the DMA is running? From a web browser (running from the server), can you perform the following query (based on your configuration):

http://35.175.118.112:9200/

This query should return information about the Elastic node. In case you are not able to retrieve any information, can you check if there is a firewall rule for port 9200?

Edit: Including a sample of DB.xml

<DataBases xmlns=”http://www.skyline.be/config/db”>
<DataBase active=”true” local=”true” type=”Cassandra”>
<ConnectString/>
<DBServer>localhost</DBServer>
<DSN/>
<DB>SLDMADB</DB>
<UID>root</UID>
<PWD>myPassword</PWD>
</DataBase>
<DataBase active=”true” search=”true” type=”Elasticsearch”>
<DBServer>10.11.12.13</DBServer>
<UID></UID>
<PWD></PWD>
</DataBase>
</DataBases>

Hi,

Yes, can access to 9200 port from my DMA, I think the issue is with db.xml config.

Hi Jose,
the DB.XML looks fine at first sight. I don’t see any errors in the DBConnection logging you posted.
I would have a look at the SLSearch logging for any pointers.

Jose,

DB.xml needs to include the configuration for Cassandra and also Elasticsearch if you are planning to use the latest version of the DataMiner. If what you posted is the complete DB.xml then that’s incorrect.

Please review the documentation at

Expert Hub – Elasticsearch

Hi,

Thanks for quick reply and thanks for all your support, I have 2 question

1. Need some changes or add something in my external server with elastic search?

2. You have template with db.xml with include casandra and elasticsearch?

Thanks

Miguel already responded to these questions, and I see that this is now solved. Thanks.
