HEYMon is a Software, Server and Application Monitoring platform. HEYMon allows monitoring requests using SQL! You can now query your enterprise to gather real-time details. HEYMon can monitor anything that is important for you: - Query a database: Look for patterns, perform queries, or generate statistics. - Parse a log file: Look for errors, or other alert conditions and statistics. - Read server metrics: Available RAM, Diskspace, processes, Windows Services - Read Windows Event logs - Monitor Security logs and web request logs - Monitor Guidewire software applications And much more! HEYMon has a Java API where you can create custom components to monitor whatever you need. The HEYMon server is supported on almost all operating systems including Linux, Windows XP/Vista/7/8, MacOSX, and UNIX. HEYMon can monitor a few systems or can scale to monitor hundreds of systems if needed. Checkout our Discussion Section for the latest news and information about HEYMon

Packetbeat is a distributed packet monitoring system that can be used for application performance management. Think of it like a distributed real-time Wireshark with a lot more analytics features. Packetbeat agents sniff the traffic between your application processes, parse on the fly protocols like HTTP, MySQL or REDIS and correlate the messages into transactions. For each transaction, the agents insert a JSON document into ElasticSearch where they are stored and indexed. The Kibana UI application provides advanced visualizations and ad-hoc queries. We have extended Kibana with our own panel types for visualizing network topologies.
