Monitoring Your Arrays

A Nimble array needs little ongoing maintenance after it is installed and configured. Even though the system runs without extensive administrative activity, it is a good idea to monitor the system regularly to make sure that everything is working correctly.

You can choose options from the NimbleOS Monitor menu to monitor the array in real time. Monitoring lets you track system trends and proactively ensure that no bottlenecks occur. Nimble's intuitive monitoring system lets you see space usage and performance at a glance.

Several monitoring options use a set of common controls. When you monitor capacity, performance, interfaces, connections, the audit log, or replication, you can specify the time interval of interest to you. Choose from:
  • Real-time, which is useful for monitoring real-time activity
  • Last 3 minutes (3M), which is useful for monitoring very recent activity
  • Last 60 minutes (1H), which is useful to determine whether an activity is a temporary or recurring condition
  • Last 24 hours (1D), which is useful for tracking activity patterns for the day
  • Last 7 days (1W), which is useful for tracking activity patterns for the week
  • Last 30 days (1M), which is useful for tracking activity patterns for the month
  • Custom, which lets you specify a time interval of interest

The selected interval determines how much data is shown. The longer the time interval, the more compressed the data appears in the graph. Use longer time intervals for tracking trends that you can use for purchasing estimates and capital expense projections.

When you monitor Capacity or Performance, you can also select one or all volumes to include in the data collection. By default, all volumes are included. However, you can limit the display to a specific volume.

The other monitoring options do not have the Real-Time and Volume common controls. Those pages provide other ways to track activity patterns.
