SAS Viya process monitoring with the healthcheck plug-in

A SAS Viya deployment is comprised of many individual processes and making sure all of these processes are up and responding is one of the primary concerns for SAS administrators. There are many approaches to this problem, most of which lean heavily on the SAS Configuration Server to assess process availability because each service is supposed to register itself in the SAS Configuration Server when it starts. Relying on the SAS Configuration Server to tell us about the services in our deployment works well as long as  each service starts well enough to register itself and that no service is stopped in such a way as to unregister itself.  If either of these events occur the SAS Configuration Server has no knowledge of the service so it is effectively ignored when reporting process availability status.  This is why administrators have to be especially careful when reviewing the Availability portlet on the SAS Environment Manager dashboard page.

 

The root problem is that the SAS Configuration Server has no knowledge of the processes that should be present but aren't. With SAS Viya 3.5, the sas-admin healthcheck plug-in provides administrators with the ability to check on processes that should be present without relying on the SAS Configuration Server. Let's take a look at this new administration feature.

 

The healthcheck plug-in has several options but in this post I am going to focus on the system-health check-status  options.  There are two modes for assessing system health

  • basic - which checks the health of the microservices
  • complex - which checks the health of microservices and applications.

This is a key difference to understand.  The complex mode not only reports on microservices but also includes checks for applications such as

  • CAS
  • SAS Message Broker
  • SAS Configuration Server
  • SAS Studio
  • SAS Drive
  • SAS Visual Analytics
  • and all of the other SAS web applications that users interact with.

For this post, I am going to focus on complex mode as it is the mode with which administrators can control the services examined by feeding it a list of services to check.

 

Let's see how the healthcheck plug-in can help an administrator assess system process availability.  After authenticating myself to the sas-admin framework, I am going to issue a sas-admin healthcheck command in complex mode to look at the processes for a healthy, fully functional Viya 3.5 deployment.  The results indicate that my deployment has 95 processes that were tested and of those 95, 1 reports as down.

 

./sas-admin healthcheck system-health check-status complex
Searching for services, applications, and infrastructure applications.

[Validating Health] .............................................................................................................

Services                   Endpoint                  Status   HTTP Status   Time of Call               Duration
Discovery Table Provider   /discoveryTableProvider   down     503           2020-02-25T11:36:59.075Z   2358

"1" of "95" health validations failed.

The following errors were generated during the execution of this program:

The following error was encountered when making an endpoint call to "/discoveryTableProvider": 1 error occurred:
  * The server failed to fulfill an apparently valid request.

 

The service that reports a 'down' status, discoveryTableProvider, is due to a licensing issue which does not allow the service to respond so the lack of a valid response is interpreted as a 'down' state.  Therefore, I can safely ignore that service when assessing my system health.

 

So far so good.  Let's add the --display-results option to display details for each of the services that were tested.  As you can see from the following output, each service has an indication of the endpoint that is used to test process availability and the results show the HTTP status of each endpoint test.  If you take a second to scroll through the information you will see that there are three sections of processes:  microservices are listed first, followed by SAS web applications, which are followed by infrastructure processes such as CAS, the SAS Infrastructure Data Server, and the SAS Message Broker.

"1" of "95" health validations failed.

The items with statuses in yellow are functioning properly, but cannot be directly verified due to their nature.

The following errors were generated during the execution of this program:

The following error was encountered when making an endpoint call to "/discoveryTableProvider": 1 error occurred:
  * The server failed to fulfill an apparently valid request.

 

So while we have a healthy system with all processes that need to be up, let's re-run the healthcheck command with the --create-yaml option which will create an output file named complexCheck.yml containing details for all of the tested processes.

 

./sas-admin healthcheck system-health check-status complex --create-yaml complexCheck.yml
Searching for services, applications, and infrastructure applications.

Discovery Table Provider /discoveryTableProvider down 503 2020-02-25T11:49:09.689Z 1804

"1" of "95" health validations failed.

 

Here is a look at the complexCheck.yml file. As the comments explain, each service has an associated endpoint for which the service to call to assess health is obtained from the SAS Configuration Server. The interesting thing though is that we now have a list of every service that should be present in a healthy deployment. We can modify this yaml file to suit our purposes such as splitting out separate checks for the web application or the infrastructure components if that suits our needs. We also have the option to add additional service checks providing we know the endpoint to call or we can specify an exact endpoint to use for any of the existing services.

 

####################################################################################################################
# A YAML file can be specified for the "complex" command.

# At the minimum, a list of service or application names must be specified.
# For every service or application listed, the program goes to Consul to find the correct head endpoint to use.
# You can specify additional endpoints to test in the YAML file. If Consul finds a match for that service or application,
# calls are made to the head endpoint in addition to making calls to all the endpoints specified in the YAML file.
# If you specify a service or application name in the file that Consul does not recognize, the program tests only
# the endpoints specified in the YAML file. If there are no endpoints, then that item is skipped.

# Pasted below is a sample format for a complex check configuration file:

Let's see how having this list of services can be especially useful to administrators.

 

Suppose one of our services is either accidentally stopped or perhaps did not start sufficiently to register itself in the SAS Configuration Server.  I'm going to simulate this by stopping the graph templates service.

 

Let's see how this is reported by the healthcheck using the default method of obtaining the list of available services from the SAS Configuration Server.

 

./sas-admin healthcheck system-health check-status complex
Searching for services, applications, and infrastructure applications.

[Validating Health] .............................................................................................................

Services Endpoint Status HTTP Status Time of Call Duration
Discovery Table Provider /discoveryTableProvider down 503 2020-02-25T11:36:59.075Z 2358

"1" of "94" health validations failed.

The following errors were generated during the execution of this program:

The following error was encountered when making an endpoint call to "/discoveryTableProvider": 1 error occurred:
* The server failed to fulfill an apparently valid request.

 

Interestingly, the results still indicate that only the expected discoveryTableProvider service is down.  If you are a very observant administrator, you might notice that the total number of health validations is now 94 instead of the 95 we had earlier with a healthy system.  If you were in a hurry and not paying close attention, you might miss that small difference and assume that everything is ok when in fact there is a missing service.

 

Let's re-run the healthcheck but this time pass it our yaml file as the list of services we want checked by adding the --source-location option to the command.

 

./sas-admin healthcheck system-health check-status complex --source-location complexCheck.yml
[Validating Health] ...................................................................................................

Services                        Endpoint                    Status   HTTP Status   Time of Call               Duration
Discovery Table Provider        /discoveryTableProvider     down     503           2020-02-25T11:57:23.201Z   1499

Infrastructure Applications                                 Status                 Time of Call               Duration
Graph Template Service                                      down                   2020-02-25T11:57:25.047Z   1

"2" of "95" health validations failed.

The following errors were generated during the execution of this program:

The following error was encountered when making an endpoint call to "/discoveryTableProvider": 1 error occurred:
  * The server failed to fulfill an apparently valid request.
The following error was encountered when making an endpoint call to "/graphTemplates": 1 error occurred:
  * The requested resource could not be found.

Aha!  Now we can clearly see that there are two services down and the total number of health validations is back up to 95.  So forcing healthcheck to look for all of the services we expect to have in our deployment appears to provide a bit of protection for administrators in cases where services do not get registered into the SAS Configuration Server.

 

So as an administrator, I can now proactively monitor processes that I know should be in my deployment without having to rely completely on the SAS Configuration Server.  This should enable me to more reliably detect process issues and help maintain more robust system health.

 

There is much more to the healthcheck plug-in that I have touched on in this post so please take a look at the documentation for a more comprehensive understanding of the many options.

 

The sas-admin command line interface is one of, if not the best, administration tools for Viya. If you are not yet familiar with sas-admin I recommend that you read Gerry Nelson's posts SAS Viya command-line interfaces for Administration and Keeping the SAS Administration Command-Line interfaces up-to-date to learn more.

Hi Scott

 

Useful blog as always.

 

I presume the simple way to get around the warning message for the /discoveryTableProvider endpoint is to comment it out from the generated yaml file?

 

Will this be fixed in a future release as it's a usefull addition to the admin toolkit?

 

regards

 

Alan

Hi Alan, thanks for reading. Yes, if you know there is a service that responds inappropriately or is not important to your monitoring needs it can be eliminated from the yaml file.
I do not believe the licensing issue would be something you would be likely to encounter. That is fortunately a problem only here at SAS where there is sometimes a lag between when new services are added and the license file we use is updated. It is, of course, possible you could see this if your company decides not to renew a SAS product in future years. In that case, the 503 error might be observable but your original solution could be used to ignore the service once the reason is known.

Thanks Scott

 

Actually, after upgrading my Viya install from v3.4 to v3.5 & updating the yaml file used by the healthcheck process, this was the only endpoint which returned an error  - exactly as per your example (all was well in Environment Manager though)

Something for Tech Suppprt I'd say?

 

Alan

Interesting...I'd say Tech Support is a good next step.

Hi Scott

 

I tried this for just this endpoint with verbose logging & as you say, the error relates to a license:

 

{
"errorCode":0,
"message":"The product license was not found.",
"details":["traceId: a4dae0be1d56cf7e","path: /discoveryTableProvider/"],
"links":[],
"version":2,
"httpStatusCode":503
}
