On the Monitoring ► Health Check Report page of the HCP System Management Console, you can select nodes that you want to include in the health check report. When you click Prepare Health Check Report, the HCP system runs a health diagnostic tool on the nodes that you have selected. For more information about these steps, see Preparing and downloading the health check report.
This health diagnostic tool executes various signatures to collect information on the health of HCP nodes in the system. Signatures are JSON files containing different shell commands that can be run on nodes in an HCP system. These signatures can be used to gather configuration information about a node and to collect data on potential issues regarding the health of a node.
Signatures can be classified into components and types. Some examples of components are replication, admin, or JVM. Types can be further classified into info and issue. Info signatures collect information regarding the configuration of nodes, such as memory configuration, version of HCP, hot fixes, and other HCP configurations. Issue signatures report if a node is either experiencing a certain issue or is at risk of experiencing that issue, such as server issues, object issues, nodes restarting repeatedly, and other general issues.
After the signatures have been executed on the selected nodes, the health check report is saved at a designated location in the output format of a JSON file, which can be downloaded at any time.
For examples of signatures in HCP health check report JSON files, see Examples of signatures in the health check report.
