Error connecting to Cassandra - com.datastax.driver.core.exceptions.InvalidQueryException
by Dhillon, Manjot
Hello, I am trying to start hawkular services, version hawkular-1.0.0.Alpha13-SNAPSHOT.
As per the documentation, I am using Cassandra version 3.0.12. On starting the hawkular service, I see the following error -
33m01:58:08,209 WARN [org.hawkular.alerts.engine.impl.CassDefinitionsServiceImpl] (Thread-239 (ActiveMQ-client-global-threads-15127043)) Could not connect to Cassandra cluster - assuming is not up yet. Cause: com.datastax.driver.core.exceptions.NoHostAvailableException: All host(s) tried for query failed (tried: apsrd6612.uhc.com/10.204.85.28:9042 (com.datastax.driver.core.exceptions.InvalidQueryException: unconfigured table schema_keyspaces))
The cassandra driver included with the hawkular service - cassandra-driver-core-2.2.0-rc3.jar, which may be causing the issue.
Thanks,
Manjot

[hawkular-alerts] Integration with Eureka
by Ashutosh Dhundhara
Hi All,
Is it possible to track UP/DOWN status of micro-services registered with
Eureka and fire email notifications if a service goes down? If yes, please
point me to right direction.

Hawkular
by Daniel Glöckner
Hi,
we're using WildFly 10.1.0 and we need more monitoring ;)
I hope this is the right mailing list.
The target picture is
-InfluxDB as TSDB for archiving performance relevant measurements
-Grafana for creating and sharing dashboards
We'd like to use "standard" tools as much as possible. JMX is a mature
standard and we'd like to use it for publishing the metrics.
Using jmxtrans (https://github.com/jmxtrans/jmxtrans) we're able to get a
lot of details about JVM and parts of WildFly.
We're lacking visibility on
-connection pools
-thread pools
-EJBs (remoting)
-web services
How could hawkular help here? I guess hawkular plugs into metrics which
are (unfortunately) not available via JMX in WildFly?
Can hawkular publish via JMX? Or write to InfluxDB?
InfluxDB is not set into stone but is the preferred solution.
Kind regards,
Daniel
