Can Web Service Companies Do Without 24×7 Dotcom-Monitor support?
Dotcom-Monitor’s global agent checks the Web service(s) to ensure that it is accessible and maintaining acceptable levels of performance. If any of these fall outside the specified parameters, the customer is notified.
1. Functional Monitoring: Dotcom-Monitor constantly checks the functionality of the service by making specifically tailored, functional calls to the site (application) server to monitor the accuracy of the results obtained in real time. It uses representative input from transactions/messages, algorithms, and results provided by the Web service company for this purpose. The monitor performs Dotcom-Monitor’s service at pre-defined intervals. Any deviations from the supplied results are promptly reported for appropriate action.
2. Performance Monitoring: Most Web service companies use SOAP (Simple Object Access Protocol) technology to architect service transactions?receipt, de-serialization, processing, serialization, and delivery. SOAP is a lightweight, stateless, XML communication protocol that lets applications exchange structured messages/transactions across the Internet. Most current SOAP implementations use HTTP binding due to SOAP’s wide availability and ability to pass through firewalls.
One of Dotcom-Monitor’s features is to determine the level of performance available from SOAP implementations using appropriate test transactions/messages. First, Dotcom-Monitor checks for latency, the round-trip time taken to send and receive a single transaction/message from the monitor server to the service server and back. High resolution timers are used to measure the time taken for each round-trip. Dotcom-Monitor repeats this check at a defined interval. For throughput, Dotcom-Monitor conducts checks to find the peak throughput available from each SOAP implementation using a number of concurrent driver threads, records the number of round-trips completed per second, and compares it to supplied norms.
Dotcom-Monitor conducts a separate exercise to measure SOAP serialization and de-serialization overheads. The test driver sends a number of customer detail records to the server. The monitor captures the times required by the server to perform serialization and de-serialization of SOAP transactions/messages. Any overall performance degradation beyond the Web service-defined boundaries are recorded and reported. A proper log of the checks made is maintained for later analysis.
Web service sites must plan for zero tolerance. While it is easy to plan and implement redundant hardware and network infrastructure, exposure lies in making flawless functional delivery within desired turnaround time, every single time. That is only possible if constant monitoring for correct functional output(s) and response time performance are maintained, and any deviations highlighted in real time for remedial action. A 24×7 website monitoring solution from Dotcom-Monitor.com is the real answer.
