System Notifications for Disk and Database Health

Metric Insights has a few different system health related email notifications. These notifications were designed for System Administrators to prevent situations that could cause a system to crash, or to notify when a database has gone offline.

The goal of this article is to help Admins understand the settings they have available.

Key Notifications about system health are set by default with every deployment — they address the following:

  1. Low disk space on primary web server;
  2. Low inode space on primary web server;
  3. Low disk space in Dataset storage engine;
  4. Dataset storage downtime.

Settings on the Info tab of Admin's User Editor allows the individual Admin to choose to receive messages about:

  1. Access Notifications;
  2. System Notifications.

See Section 3 below for more information.

1. System Variables Controlling Disk and Inode Notifications Options

Occasionally files on your Metric Insights server will become numerous, utilizing precious disk space. By default, the system is set to notify Support Admin users when disk space goes below the percent set via specific Variables.

Access Admin > System > System Variables

  1. MAX_USED_DISK_SPACE_PERCENT. Set this field to the maximum percentage that your System Disk space can use before Notifications (SEND_LOW_SPACE_EMAIL) are sent.
  2. MAX_USED_INODE_PERCENT. Set this field to the maximum percentage that your INODE Disk space can use before Notifications (SEND_LOW_INODE_SPACE_EMAIL) are sent.

2. System Variables Controlling Storage Health Notification Options

Database status (Admins will be notified if the database goes down) and low disk space Notifications are sent via email. Interval can be set via the following Variables.

  1. STORAGE_HEALTH_CHECK_INTERVAL: Set it to the interval (in seconds) for system to check Health of all your Data Storage systems.
  2. SEND_STORAGE_HEALTH_EMAIL: Set to 'Y' in order for System Admin to receive notifications.

3. Admin Options

Open the User Editor of the Administrator's account and go to Info tab.

  1. Receive Access Notifications: When selected, sends the Admin emails about problems such as access denied to a page or missing Privileges and any related Access Request emails.
  2. Receive System Notifications: When selected, allows Admins to receive emails about such problems as low disk space, low inode space, and data storage health.
