Using templated message formats with customisable placeholders, run in configurable sequences that can selectively reuse data between steps, must allows more intelligent testing of syslog receivers with realistic data, as well as longer soak testing and stress testing.

must was created to fill a gap found when trying to stress test Splunk as real, indexable and meaningful data was needed.

must will (eventually) be provided as a standalone tool that uses XML configs (for quick use and consultancy etc) and as a web-based tool (for more permanent/pretty deployment (with historical reporting and live stats).

Infrastructure and application monitoring for Azure Icon

Monitor your Azure® infrastructure, application, and systems performance side by side in a single enterprise-monitoring tool

So, you moved your applications and servers to Azure, but are they running any better and are you able to justify the investment? Without proper monitoring, you’re left guessing if application and server performance has improved, and when issues arise, you’re left scrambling to locate the root cause. SolarWinds® Server & Application Monitor (SAM) can monitor your Azure workloads side by side with your on-premises workloads to help ensure optimal application performance.
