Germain is now able to monitor additional metrics and events while monitoring an Android App, such as:

• Crash
• Page navigation
• Transactions

​

Monitoring & Analytics - Node.js

​

Description

Germain is now able to monitor performance of NodeJS application and send alert (email/sms) for any issue. Areas/entities that Germain monitors and provides insights on while monitoring a NodeJS application, in the case you use Node.js as an application server (on the other end, if you are using Node.js as a front-end, the below list of benefit may or not apply and all you need to do to enable that monitoring is to declare our 2 javascripts within your node.js app, and we can provide more details if needed):

Show all 20

• Express monitoring
• Heap size and heap usage monitoring for node.js process
• Integrate existing generic monitoring features
• Load average monitoring
• Logging integration
• MarkoJS app name extractor
• MultipleResolves monitoring
• Network / incoming and outgoing HTTP monitoring
• OS monitoring
• Promises rejection monitoring (Unhandled promise rejections, etc).
• Startup duration monitoring
• Tagging requests from UX and extract on node.js
• Transaction monitoring
• Warning monitoring (bad coding practices, bugs, or security vulnerabilities),

and few aspect of the management/configuration of that feature:

• Configuration for the session extractors
• NPM deployment
• Email Alert (generic, preconfigured for NodeJS, and configurable)

​

Installation & Configuration

Node.js

​

Support

Node.js 8.0.0 and above.

​

Monitoring & Analytics - Java & JVM (deeper insights)

​

Description

Re-designed and enhanced germain Germain’s Java & JVM monitoring feature. Customers can now monitor the execution duration of any java method / service through code injection. Our past/old Java monitoring capability was just doing sampling CPU profiling (i.e., check every N milliseconds to see which function is currently active and accumulate that over time). Code injection provides a significantly better accuracy and greater depth when it comes to identifying slow or inefficient java methods. Features:

​

Benefits

Greater depth of insights to help identify bottlenecks that prevent a Java application to be available or be fast

​

Performance Impact

Small/negligibleperformance impact on the monitored application. Here are some details about the load tests we performed on our labs, to understand how much of an impact this newly enhanced java monitoring mechanism may cause on a monitored application Test scenario & result: 50 concurrent users browsing germain Germain dashboard and config console + 300 users using a CRM web application and being monitored by germain Germain engines & js scripts) CPU Increase: 0.5% increase in CPU Memory increase: < 50 MB Response time (average overhead / request) HTTP requests: +0.26ms Generic Java method: +0.35ms SQL statements: +0.37ms SQL Prepared statement: +1.5ms

​

Configuration

Java Operational Experience Intelligence

​

Example

RCA for Inbound Java request > custom java method call > SQL query execution

• and all these other benefits and visualizations are still available: Monitoring & Analytics - Java & Weblogic
• and there is more to come in February and March of 2019 - stay tuned…🙂

​

Monitoring & Analytics - User Replay

​

Description

As announced last month, we have released a re-designed and enhanced version of our Real User Session Replay feature. Here is below an example of User Session Replay for a Siebel CRM (we added that video example a week after announcing the 12/31/19 release notes.

​

Monitoring & Analytics - IIS web server

​

Description

Enhanced IIS monitoring and now provide:

​

Example

​

Monitoring & Analytics - Oracle KB

​

Description

Synthetic Transaction against Oracle Knowledge Base management (https://www.oracle.com/applications/knowledge-management.html), is now preconfigured in OOTB Germain

​

Benefit

Detect availability or performance issue with Oracle Knowledge Base management

​

Monitoring & Analytics - Siebel - Error by OM

​

Description

Added OOTB a portlet that views siebel error by object manager…this was a 5min job, but FYI it is available in Germain 8.5.15 onwards.

​

Monitoring & Analytics - Siebel - SQL Statement - raw & bound

​

Description

Germain now reports RAW and BOUND SQL statement. that is currently configured for Siebel and the Siebel log level have to be set accordingly. And as a reminder and as an alternative, SQL statements are also monitored directly from within the database (Oracle, SQL srvr, DB2 UDB, MySql, etc).

​

Benefit

Time saving for DBAs that need these to tune slow SQL statements.

​

Example

​

Monitoring & Analytics - compliance & audit review

​

Description

One of our clients needs to provide data from its CRM application to another system for Compliance review & Auditing. Specifically, client is planning to query Germain datamart to pull out data and send it to its compliance repository. Some of the data that is going to be pulled out of the Germain datamart:

Show all 18

• Unexpected service stop
• Log(Disk) storage capacity exceeded
• Saved browsers (which browsers accessed system)
• Administrator Activities
• All activities while logged in as administrator
• System start-up
• System shut-down
• Log service start
• Log service stop
• Changes to system (CRM configuration changes, etc)
• Change of CRM logging level
• etc

​

Monitoring & Analytics - Plugins available in germain APM

We updated the list of technologies we have configured Germain for: https://germainux.com/plugins

​

Maintenance - MySQL for germain APM

Description FYI. For some of our AWS cloud customers using MySQL as datastore for Germain, and with almost no tuning, we are reaching 4k inserts per second in MySQL (2kb insert size in average). (Reminder that Germain currently supports:

​

Maintenance - SiteMinder support

​

Description

UX through siteminder url, to be able to securely monitor User Experience of an application using a public URL

​

Maintenance - Tuning Tip for Spring Boot (if using germain APM < 8.5.15)

​

Issue

Our Spring Boot service (used for Session Replay) was crashing running out of memory generating this exception: Exception:
2019-01-26 17:44:00,006 INFO SessionTrackingService - Processed 130 sessions. - [pool-2-thread-1] 2019-01-26 17:44:03,733 ERROR FileBackedStorageEngine - Failed to allocate a direct buffer for a FileChannel write. Consider increasing the -XX:MaxDirectMemorySize property to allow enough space for the FileChannel transfer buffers - [Ehcache [_default_]-1147] 2019-01-26 17:44:04,633 ERROR FileBackedStorageEngine - Failed to allocate a direct buffer for a FileChannel write. Consider increasing the -XX:MaxDirectMemorySize property to allow enough space for the FileChannel transfer buffers - [Ehcache [_default_]-1148] 2019-01-26 17:44:58,060 INFO SessionCache - Flushing stale sessions before: 2019-01-26T16:44:58.060 - [pool-2-thread-1] 201

​

Tuning solution

Please apply this tuning recommendation to your environment if you are on Germain 8.5.14 or prior: Add parameter -Djdk.nio.maxCachedBufferSize=262144to the session services to prevent them from caching large files in memory in these files: Windows: $germain/…/ServiceDistribution/src/main/bin/GermainSessionTrackingServices.xml Unix: $germain/…/ServiceDistribution/src/main/bin/session-tracking/GermainSessionTrackingServices.xml Java options would look like this: …/… JAVA_OPTS=“-Xms2g -Xmx4g -XX:+CrashOnOutOfMemoryError -Djdk.nio.maxCachedBufferSize=262144” …/…
