Hi All,  
I am new to logstash.  
There was a requirement where client want to monitor few database servers using logstash and sentinel.

I am able to connect to Sentinel but I am not able to fetch data from oracle database.  
Java version - 17  
Logstash - 7.9.12

Conf.file  
input {  
jdbc {  
jdbc\_validate\_connection =\> true  
jdbc\_connection\_string =\> "jdbc:oracle:thin:@\</database ip\>:\</listener port\>/sid"  
jdbc\_user =\> ""  
jdbc\_password =\> ""  
jdbc\_driver\_library =\> "/apps1/log-jars/ojdbc8.jar"  
jdbc\_driver\_class =\> "Java::oracle.jdbc.driver.OracleDriver"  
schedule =\> "\* \* \* \* \*"  
statement =\> "SELECT \* FROM V$ACTIVE\_SESSION\_HISTORY WHERE SAMPLE\_TIME \> :sql\_last\_value"  
}  
}  
output {  
stdout { codec =\> rubydebug }  
}

Error I am getting:

][ERROR][logstash.inputs.jdbc][main][92f73b9c6778569ee3b7453413d24903e7837320354d5cc0dec0d2a2ce629776] Unable to connect to database. Tried 1 times {:error\_message=\>"Java::JavaSql::SQLRecoverableException: IO Error: The Network Adapter could not establish the connection (CONNECTION\_ID=CzezbmIgSu2YDvCrpnF07w==)"}

Please help me on this. I am using linux redhat 8.
