HashiCorp Nomad Monitoring and Performance Management
Nomad is an open source container management and job scheduler solution, mainly developed by HashiCorp. Instana Nomad Monitoring offers comprehensive performance management for the highly dynamic environment of scheduled jobs with short-lived container or virtual machine lifecycles, as well as the technologies and health of applications running on a Nomad controlled infrastructure.
To help optimize application performance and automate performance management workflows, Instana’s Nomad Monitoring goes beyond simple metrics to provide a comprehensive set of management and monitoring features:
- Discovery of started Nomad instances and services
- Automatic code instrumentation of 10 languages including .NET, Java and Python
- Automatic mapping and visualization of Service dependency maps
- End-to-end tracing of all requests across all systems
- Application and service health monitoring
- Job starts, stops and runtimes
Effective Nomad Monitoring requires performance visibility for the physical or virtual host, containers and orchestration, job instances, and any applications and services using the instance.
Instana is the quickest and easiest way to monitor Nomad jobs across the stack to deliver comprehensive job insights. The Instana agent automatically discovers all Nomad instances, deploys the necessary application and Nomad monitoring sensors; then begins tracing jobs and cross-system requests. Instana also automatically determines the health of Nomad instances and jobs.
Monitoring Nomad Performance
Once deployed, the Instana Agent automatically identifies all running Nomad nodes – then automatically deploys and configures Instana’s Nomad Monitoring sensor. Additional Instana infrastructure and application monitoring sensors are deployed for running jobs and their virtualized or containerized applications. Instana’s curated knowledge base already knows what performance metrics are relevant for collection and how to collect them. To monitor Nomad health, additional metrics are also collected. Since Instana’s automatic configuration collects all relevant information, monitoring Nomad clusters couldn’t be easier.
To determine overall service health, the Instana Nomad Monitoring sensors also collect KPIs on the monitored environment to determine its health status.
With the help of Artificial Intelligence (AI) and health signatures from the curated knowledge base, Instana automatically detects issues with individual Nomad instances or clusters and automatically files service incidents. Instana automates incident escalation (based on Severity, among other things) and root cause identification, helping you solve issues before users are impacted.
Nomad Configuration Monitoring
In addition to performance and health data, Instana’s Nomad Monitoring sensor also collects configuration data, allowing Instana to analyze and correlate configuration data and changes with application and service performance information.
All Nomad performance and configuration information is summarized in a single Monitoring Dashboard, showing all relevant information in a single place for easy problem-solving and performance optimization.
Nomad performance monitoring centers around cluster and node metrics, job statuses and measurements, as well as their interactions with other services or data stores. Instana automatically identifies and collects the relevant service metrics.
Nomad Monitoring Data
Instana Nomad Monitoring includes two types of data; Performance Metrics and Configuration Data:
|Performance Metrics||Configuration Data|
