Monitoring


Why do we need diagnostic tools?


Let’s slow that down a bit


Fixing problems in a dev environment


Fixing problems in production environments

Logging

Monitoring


Code Tracing


Code TracingReproducing an issue is not always possible...

▶ Dependency on specific SESSION state

▶ Dependency on specific database state

▶ “Replaying” the request is risky or impossible

Zend Code Tracing can capture the entire execution flow

▶ ...and, it is efficient enough to be used in most production environments!

“Hindsight is always twenty-twenty.”- Billy Wilder




Job Queue


Job Queue – A Common Execution Flow


Why use the Job Queue

• Very easy to set up

• Very easy to use API

• Very easy to scale

• Job execution can be easily deployed as part of your application


Not good for queuing

Much better for queuing


A useful practice:

• Create a generic handler

• Pass objects to be executed to that handler


Session Clustering

Architectural Overview


Failure Handling


Scalability & Cloud Readiness

• Session Clustering provides a Graceful Shutdown mechanism When a machine is shut down, it will transfer all it’s

sessions to a different server in the cluster

All cluster members will know to use the replacement server while the original owner is down

This process rarely takes more than 30 seconds

• Graceful Shutdown allows shutting down machines permanently or for maintenance without losing sessions

• Allows scaling down in addition to scaling up – Cloud ready!


Zend Server Cluster Manager


What is Zend Server Cluster Manager?

• A central management point for a cluster of Zend Servers

• Central Configuration Management

• Central Monitoring

• Session Clustering

Question

• For a free copy of Zend Studio…

• Is it generally a good practice to use Zend Server Code Tracing in a production environment?
