Sematext Scalable Performance Monitoring is brand new and we are
working on gathering frequently asked questions - let us know if you
Q: What should I do if I can't find the answer to my question in the FAQ?
Q: How do I enable JMX in HBase?
Q: Do I need to add a separate System for each HBase server/node I want to monitor?
A: No, one System is enough. Think of an SPM
"System" as a "HBase Cluster". Thus, to monitor N HBase servers that
belong to the same cluster you would create just a single SPM
System and use its Token in SPM configuration file on all HBase
servers that are a part of this cluster.
Q: Why don't some graphs have any data?
A: There could be 2 possible reasons:
- Some metrics are for RegionServers (HBase slaves), some for
HBase Master. Thus, if you select the Master node in the UI,
graphs that contain Slave-specific metrics will be blank and
- Different versions of HBase provide
different metrics. Thus, if you have an older version of HBase,
it may not be providing all metrics that SPM collects and
Q: Which versions of HBase does SPM support?
A: SPM works with HBase 0.90 and 0.92. We
have not tested it with HBase 0.94 yet, but we believe SPM will
work with 0.94, too.
