I rebooted my server and now I don't see any data in my graphs. What should I check

I am using SPM for Solr and I don't see any data on Solr and JVM reports, what is the problem
A: You should probably enable JMX in your Solr. Add or uncomment the <jmx /> directive in solrconfig.xml and restart Solr. See http://wiki.apache.org/solr/SolrJmx for more info.
I am using SPM for Solr and I don't see any data only in Solr Components or Errors reports, what should I do
A: Most likely you are using standalone variant of Solr monitor. In that case, SPM monitor can't collect metrics which are available only when running in-process. If so, switch to in-process (javaagent) version of SPM monitor.
Elasticsearch Monitoring
Why doesn't the number of documents I see in SPM match the number of documents in my Elasticsearch index

Can I see metrics for non-Scala/JVM Kafka Producers and Consumers

Alerts
Can I send alerts to HipChat, Slack, Nagios, or other WebHooks
A: SPM let's one configure arbitrary Webhooks to call with Alert event information when Alert events are triggered. The details for HipChat integration are described here.
What are Threshold-based Alerts
A: Threshold-based alerts are classic alerts where you choose a metric and a numeric value (a threshold) that, when reached or crossed, triggers an alert.
What is Anomaly Detection
A: Anomaly Detection uses a number of statistical algorithms to determine if a metric has become anomalous, meaning that its recent values have become significantly different from the "base" – the normal/typical values of that metric. An example of an anomaly is a sudden spike or a sudden dip in a metric value. SPM can trigger alerts when such anomalies are detected.
What are Heartbeat Alerts
A: Heartbeat Alerts are extremely useful for keeping an eye on your applications. You create a single Heartbeat Alert for each SPM App. From then on, SPM will watch all instances of your application that are a part of that SPM App. Should SPM not hear from any one of your application's instances for more than N minutes, it will alert you. N can be as low as 2 minutes and you choose it yourself when you create a Heartbeat Alert.
