Aurora_mon is an in-guest application monitoring agent that integrates with vSphere HA. You use aurora_mon to monitor the state of applications and services.

Within Data Director, you use aurora_mon to monitor the services and resources of components of Data Director.

For the Central Management Server (CMS), you use aurora_mon to monitor the state of the following applications and services:

Tomcat running the CMS

CMS Postgres DB

DHCP client daemon (dhcpcd)

Amount of disk space for mount points, with specified thresholds. When the threshold is exceeded (for example, 80% of the data disk), an alarm is generated.

For the DB Nameserver virtual machine, you use aurora_mon to monitor the state of the following applications and services:

LDAP

DHCP client daemon (dhcpcd)

Amount of disk space for mount points, with specified thresholds. When the threshold is exceeded (for example, 80% of the data disk), an alarm is generated.

For the DB virtual machines, you use aurora_mon to monitor the state of the following applications and services:

DB (MySQL, Oracle, Postgres, and SQL Server )

DBVM Updater

Archive maintenance

aurora agent

Stats daemon (Postgres only)

DHCP client daemon (dhcpcd), and network connectivity (by pinging the gateway)

IP Whitelist logging daemon

Amount of disk space for mount points, with specified thresholds. When the threshold is exceeded (for example, 80% of the data disk), an alarm is generated.

The complete set of applications and services aurora_mon monitors is defined in /opt/aurora/ha/etc/aurora_mon_conf.d/*.conf.

At the highest level, you configure parameters to enable aurora_mon to start, stop, and monitor applications. You specify the start, stop, and monitor commands as shell scripts or operating system executable files that aurora_mon can invoke. Application developers can implement these commands according to the needs of their environment. Other parameters enable you to specify how often to monitor an application and what action to take. See aurora mon parameters for a description of aurora_mon configuration parameters.
