Systems monitoring in case of lost network connection in SaaS model

A computer system for monitoring computing devices by a monitoring server, the computer system comprising:

• a memory;
• and
• a processor in communication with the memory, wherein the computer system is configured to perform a method comprising:
• receiving a first alert message at a monitoring console if a condition is detected by the monitoring server, wherein the condition is defined in an alert definition, and wherein status messages being sent from the monitored computing devices are initially directed to the monitoring server via a network communication link between the computing devices and the monitoring server when the communication link is online, wherein an alert cache system which is part of the computing devices does not receive the status messages directed to the monitoring server when the network communication link is online, and wherein the monitored computing devices reside at a first geographical location and the monitoring server resides at a second geographical location, the first geographical location being different from the second geographical location;
• communicating the alert definition to the alert cache system;
• based on the network communication link between the computing devices and the monitoring server failing, performing the following:
• redirecting the sending of status messages from the computing devices, the redirecting providing that status messages being sent from the monitored computing devices are directed to the alert cache system instead of to the monitoring server via the network communication link, wherein based on the network communication link failing, the alert cache system commences receipt of the status messages;
• storing, in the alert cache system, status messages sent from the monitored computing devices to the alert cache system until the network communication link is back online;
• and
• sending a second alert message from the alert cache system to the monitoring console if a condition is detected by the alert cache system that is based on the communicated alert definition from the monitoring server to the alert cache system;
• and
• based on the network communication link between the computing devices and the monitoring server going back online, sending the stored status messages to the monitoring server and reverting the sending of status messages from the monitored computing devices to provide that status messages being send from the monitored computing devices are again directed to the monitoring server via the network communication link, wherein the alert cache system again does not receive the status messages directed to the monitoring server when the network communication link is online.

A computer program product for monitoring computing devices by a monitoring server, the computer program product comprising:

• a computer readable storage medium readable by a processing circuit and storing instructions for execution by the processing circuit to perform a method comprising:
• receiving a first alert message at a monitoring console if a condition is detected by the monitoring server, wherein the condition is defined in an alert definition, and wherein status messages being sent from the monitored computing devices are initially directed to the monitoring server via a network communication link between the computing devices and the monitoring server when the communication link is online, wherein an alert cache system which is part of the computing devices does not receive the status messages directed to the monitoring server when the network communication link is online, and wherein the monitored computing devices reside at a first geographical location and the monitoring server resides at a second geographical location, the first geographical location being different from the second geographical location;
• communicating the alert definition to the alert cache system;
• and
• based on the network communication link between the computing devices and the monitoring server failing, performing the following:
• redirecting the sending of status messages from the computing devices, the redirecting providing that status messages being sent from the monitored computing devices are directed to the alert cache system instead of to the monitoring server via the network communication link, wherein based on the network communication link failing, the alert cache system commences receipt of the status messages;
• storing, in the alert cache system, status messages sent from the monitored computing devices to the alert cache system until the network communication link is back online;
• and
• sending a second alert message from the alert cache system to the monitoring console if a condition is detected by the alert cache system that is based on the communicated alert definition from the monitoring server to the alert cache system;
• and
• based on the network communication link between the computing devices and the monitoring server going back online, sending the stored status messages to the monitoring server and reverting the sending of status messages from the monitored computing devices to provide that the status messages being sent from the monitored computing devices are again directed to the monitoring server via the network communication link, wherein the alert cache system again does not receive the status messages directed to the monitoring server when the network communication link is online.
