Troubleshooting

Our heroix rules engine stopped.

Are there any resources or hints on debugging this?

Any help is greatly appreciated.

Computer Rule Engine 127.0.0.1:7222
Port 7222
State Stopped
Startup Log Firenze Home: C:\Program Files\Longitude
ERROR: Error in starting Engine property manager.
caused by: com.heroix.firenze.common.config.ConfigException: Unable to load properties file, exception thrown while loading
com.heroix.firenze.common.config.FirenzeConfig.loadPropertiesFromFile(FirenzeConfig.java:100)

Longitude writes the metrics it collects to tables in a backend MaxDB database. When an application is first monitored, it creates a table with predefined column sizes for each metric which specify the number of digits and amount of precision to use for the data.

For example, the error message:

Number 148694592 is too big for column size 10 having precision 2

means that the data being collected (148,694,592.00) is being written to a column with a maximum value of 99,999,999.99 (10 digits total, with 2 digits of precision).

Firefox 3.6 requires Selenium 1.04 or higher. If you are using these versions of Firefox and Selenium to create Internet macros for the Internet application, you will get an error message that Longitude is "unable to delete" a file named "parent.lock".

This is fixed by an updated selenium-server.jar file. To put this in place, do the following:

1. Download the updated selenium-server.jar file.
2. Stop the Longitude services.

In Longitude 6.2, if you suspend all collections in Manage Monitoring, the MONITOR APPLICATION, REMOVE APPLICATIONS, and SUSPEND APPLICATIONS buttons are not available on the page, and you will see the following message:

Data is not loaded. Please try again in a few minutes.

To display the suspended servers and the management buttons:

1. Go to the main Monitoring page.
2. In the Manage Applications menu, click the Add link
3. Register a ping transaction for a server that is not suspended

The full Management Console installation kit has an agent installation option. Some agents installed using this option in the 64 bit installation kit may have the following problems:

• In Administration >> Component Management >> Display Status, the agent status is displayed as red
• In Manage Monitoring, a test connection to the agent is successful, but you are unable to register collections

The following steps will fix this problem:

1. Log on to the agent computer with a Local Administrator account
2. Stop the Longitude services

While in Manage views if I click on a view to edit it and either add a filter or modify the description field the setting for images is set to default for that view. This happens even though I do NOT select update image button. So any placement of icons is lost and any custom background I set is set to the default map.

The SQL2005 application in Longitude collects data using both WMI and SQL Queries running over a JDBC connection. The following collections are made using JDBC:

• FailedJobs
• FrequentQueries
• Index
• LongestJobs
• WorstQueries

If the JDBC based collections are failing, try the following debug steps:

1. If the error message you receive includes a "Connection timed out" message, try restarting the Statistics Server, and then register the SQL2005 application again for the instance you would like to monitor.

The Sql_Processes task or the Sql_Locks task from SQL2000 application is failing in v6.2:

You got an email alerting you that either or both of these tasks are failing.
