Morpheus Health

../../_images/morpheusHealth500.png

The Morpheus Health section provides an overview of the health of your Morpheus appliance. It includes an appliance health summary in the following areas:

  • CPU: Appliance CPU usage is checked. If usage is greater than 50%, this indicator will be in a yellow or warning state. If Morpheus is unable to complete the check, it will be in a red or error state. Depending on appliance performance and how frequently this indicator is in a warning state, it may be necessary to upgrade to increase CPU. The Overall health indicator will mirror the CPU health indicator

  • Memory: If swap usage is above 60% or Morpheus memory usage is above 95%, this indicator will be in a yellow or warning state. If Morpheus is unable to complete the check for any reason, it will be in a red or error state. Depending on appliance performance and how frequently this indicator is in a warning state, it may be necessary to increase swap, upgrade the appliance to add memory, or consider a different appliance architecture for those using single-node appliances

  • Storage: If utilization of the filesystem mounted at “/” exceeds 80%, this indicator will be in a yellow warned status. Above 90% will put this indicator in red or error status

  • Database: The database is checked. If the number of database connections exceeds the configured maximum number of connections or if any test queries are reported as being slow, this indicator will be in a yellow or warning state. If Morpheus is unable to communicate with the database, it will be in a red or error state. In the database section further down the page, you can check the number of maximum used connections against the number of max connections. In the case of database connections exceeding the maximum, consider increasing the maximum settings connection

  • Elastic: Elasticsearch is polled for the health status of each index. If any indices are not reporting a “green” health status, this indicator will be in a yellow or warning state.

  • Queues: RabbitMQ queues are checked. Any queues containing more than 1000 messages are considered to be in an error state. Appliance Queue health is given in a yellow or warning status when any queues are in such an error state. In the Queues section further down the page you can see the individual Queues listed and which have messages piling up. When the appliance is unable to complete the check for any reason, this indicator will be in a red or error state

Health Levels

Health levels provide a live representation of the current memory and CPU load on the appliance. Bear in mind that in an HA appliance, this data will be specific to the appliance node you happen to be using. By default, Morpheus does not include any endpoint or UI tool which can show you the currently used app node. However, a plugin has been developed which can surface this information if needed. See this thread in the Morpheus official forums for additional details about accessing and using the plugin.

  • Morpheus CPU: Instantaneous amount of CPU capacity in use by Morpheus processes

  • System CPU: Instantaneous amount of CPU capacity in use by all processes

  • Morpheus Memory: Instantaneous amount of system memory currently in use by Morpheus processes (see the Knowledge Base article linked in the TIP box below for more information on how Morpheus claims and manages available memory)

  • System Memory: Instantaneous amount of total system memory currently claimed (this is commonly a high percentage, see the TIP box below)

  • Used Swap: Instantaneous amount of total available system swap in use

  • Storage: The instantaneous percentage utilization of the filesystem mounted at “/”

Tip

It’s common to see a high percentage of system memory being used due to the way Morpheus allocates and manages memory. If Morpheus is performing well, high system memory use is not necessarily an indicator that any action needs to be taken.

Morpheus Logs

The Morpheus logs section aggregates appliance-specific logs into one list. If needed, users can export the logs by clicking EXPORT. This action triggers a download containing the last 10,000 log entries as a .log file.
