Abstract

Techniques for managing an upgrade operation comprising multiple upgrade process executing on multiple host machines (or hosts) for upgrading software applications on the multiple hosts. Techniques are disclosed for managing notifications that are generated by the multiple upgrade processes during execution, and more particular, techniques for reducing the number of notifications that are sent to a user. The techniques include: only sending a subset of the generated notifications to a user, the subset being selected at the host machines based upon notifications level criteria specified by the user for the host machines; consolidating multiple generated notifications into a fewer number of consolidated notifications and only sending consolidated notifications to the user; combination of criteria-based selection and notifications consolidation.

Claims

1. A method comprising:

executing, on each host machine of a plurality a host machine, at least one upgrade process from a plurality of upgrade processes;

determining, from among the plurality of host machines, a particular host machine as a notification agent for the plurality of host machines, wherein the particular host machine executes a third upgrade process of the plurality of upgrade processes;

receiving, by the particular host machine from the plurality of host machines, a first notification, the first notification generated by a first upgrade process of the plurality of upgrade processes executed by a first host machine from the plurality of host machines, the first upgrade process for upgrading a first software application on the first host machine, the first notification comprising information related to the first upgrade process;

generating, by the particular host machine, a single notification by consolidating the first notification and a second notification, the second notification generated by a second upgrade process of the plurality of upgrade processes executed by a second host machine from the plurality of host machines, the second upgrade process for upgrading a second software application on the second host machine, the second notification comprising information related to the second upgrade process;

sending, by the particular host machine, the single notification to a user instead of the first notification and the second notification; and

subsequent to sending the single notification, selecting, from among the plurality of host machines, a different particular host machine other than the particular host machine, as the notification agent for the plurality of the host machines.

2. The method of claim 1, wherein the first notification is generated before the second notification.

3. The method of claim 1, wherein the plurality of upgrade processes are part of an upgrade operation, and the method further comprising:

maintaining the particular host machine as the notification agent during the upgrade operation.

4. The method of claim 1, wherein the plurality of upgrade processes are part of an upgrade operation, and the method further comprising:

changing the notification agent during the upgrade operation.

5. The method of claim 1, wherein the determining is based upon:

a type of notification of the first notification or the second notification;

or

a start time of the first upgrade process, the second upgrade process, or the third upgrade process.

6. The method of claim 1, further comprising:

determining whether to send the single notification to the user, wherein the determining is based upon a notification level of the single notification and a user-specified level for the plurality of host machines, wherein the single notification is sent to the user in response to determining to send the single notification to the user.

7. The method of claim 1, wherein the single notification is sent to the user after a predefined delay after an upgrade process of the particular host machine begins.

8. A non-transitory computer-readable storage medium storing a plurality of instructions executable by one or more processors, the plurality of instructions when executed by the one or more processors causes the one or more processors to:

execute, by a particular host machine of a plurality of host machines, a third upgrade process from a plurality of upgrade processes, wherein each host machine of the plurality of host machines executes at least one upgrade process from the plurality of upgrade processes;

determine, the particular host machine of the plurality of host machines, as a notification agent for the plurality of host machines;

receive, by the particular host machine, a first notification, the first notification generated by a first upgrade process of the plurality of upgrade processes executed by a first host machine, the first upgrade process for upgrading a first software application on the first host machine, the first notification comprising information related to the first upgrade process;

generate, by the particular host machine, a single notification by consolidating the first notification and a second notification of the plurality of upgrade processes, the second notification generated by a second upgrade process executed by a second host machine, the second upgrade process for upgrading a second software application on the second host machine, the second notification comprising information related to the second upgrade process;

send the single notification to a user instead of the first notification and the second notification; and

subsequent to sending the single notification, select, from among the plurality of host machines, a different particular host machine other than the particular host machine, as the notification agent for the plurality of the host machines.

9. The non-transitory computer-readable storage medium of claim 8, wherein the first notification is generated before the second notification.

10. The non-transitory computer-readable storage medium of claim 8, wherein the plurality of upgrade processes are part of an upgrade operation, and the plurality of instructions when executed by the one or more processors further causes the one or more processors to:

maintain the particular host machine as the notification agent during the upgrade operation.

11. The non-transitory computer-readable storage medium of claim 8, wherein the plurality of upgrade processes are part of an upgrade operation, and the plurality of instructions when executed by the one or more processors further causes the one or more processors to:

change the notification agent during the upgrade operation.

12. The non-transitory computer-readable storage medium of claim 8, the plurality of instructions when executed by the one or more processors further causes the one or more processors to:

subsequent to sending the single notification, reassigning a different host machine as the notification agent.

13. The non-transitory computer-readable storage medium of claim 8, wherein the determining is based upon one or more of the following:

a type of notification of the first notification or the second notification;

or

a start time of the first upgrade process, the second upgrade process, or the third upgrade process.

14. The non-transitory computer-readable storage medium of claim 8, wherein the plurality of instructions when executed by the one or more processors further causes the one or more processors to:

determine whether to send the single notification to the user, wherein the determining is based upon a notification level of the single notification and a user-specified level for a plurality of host machines including the first host machine and the second host machine, wherein the single notification is sent to the user in response to determining to send the single notification to the user.

15. The non-transitory computer-readable storage medium of claim 8, wherein the single notification is sent to the user after a predefined delay after the third upgrade process begins.

16. A system comprising:

one or more processors; and

a non-transitory computer-readable medium including instructions that, when executed by the one or more processors, cause the one or more processors to;

execute, by a particular host machine of a plurality of host machines, a third upgrade process from a plurality of upgrade processes, wherein each host machine of the plurality of host machines executes at least one upgrade process from the plurality of upgrade processes;

determine, the particular host machine of the plurality of host machines, as a notification agent for the plurality of host machines;

receive a first notification, the first notification generated by a first upgrade process of the plurality of upgrade processes executed by a first host machine, the first upgrade process for upgrading a first software application on the first host machine, the first notification comprising information related to the first upgrade process;

generate a single notification by consolidating the first notification and a second notification of the plurality of upgrade processes, the second notification generated by a second upgrade process executed by a second host machine, the second upgrade process for upgrading a second software application on the second host machine, the second notification comprising information related to the second upgrade process;

send the single notification to a user instead of the first notification and the second notification; and

subsequent to sending the single notification, select, from among the plurality of host machines, a different particular host machine other than the particular host machine, as the notification agent for the plurality of the host machines.

17. The system of claim 16, wherein the instructions, when executed by the one or more processors, further cause the one or more processors to:

determine whether to send the single notification to the user, wherein the determining is based upon a notification level of the single notification and a user-specified level for a plurality of host machines including the first host machine and the second host machine, wherein the single notification is sent to the user in response to determining to send the single notification to the user.
