Products :: SPM :: SPM for HBase :: FAQ

Sematext Scalable Performance Monitoring is brand new and we are working on gathering frequently asked questions - let us know if you have any!

Q: What should I do if I can't find the answer to my question in the FAQ?
A: Please contact our support.
Q: How do I enable JMX in HBase?
A: Please see HBase Metrics page for instructions.
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:
  1. 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 vice-versa.
  2. 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 graphs.
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.
