Work around

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

We have seen some cases in Longitude 6.2 in which the CPU on a Longitude agent will spike when collecting data for Internet Macros. The Firefox instances used to collect data for the Internet Macro do not close correctly, leaving orphaned Firefox processes on the agent.

Until a patch is available, this problem can be addressed by restarting the Longitude Statistics Server component. This should kill the orphaned Firefox processes, but you may need to check the Longitude server directly and close dialog boxes for Firefox errors.

Longitude's SNMP Studio has an option to create reports based on queries against Longitude's SAP database. Longitude 6.1 and higher use a newer version of the database which may produce a syntax error if a column alias is used in a "group by" in the query. For example, the original definition may have:

group by md.manageddevicedns, mobject

as the "group by" clause in the query, where mobject is defined in the select statement as: "select mo.objectname as mobject". The query should be modified to:

group by md.manageddevicedns, mo.objectname

Longitude upgrades are not cumulative - that is, if you're at Longitude 5.0, and you want to upgrade to 6.1, you need to run incremental upgrades from 5.0 -> 5.1, 5.1 -> 6.0, and 6.0 -> 6.1. The upgrade instructions are posted at the community and in the Longitude help.

For Longitude agent installs, if feasible, it's faster to uninstall the older agent, and just do a clean install of the most recent Longitude version.

There can be a problem viewing the detail page for a down SLA in IE - when you try to get the details, the status bar will display "Downloading data http://0.0.0.0/...", and then the display an incorrect detail report.

The work around for the "Downloading data http://0.0.0.0/..." message in IE for SLA details is:

1) Hit Ctrl-F5 - you should see "Done" in the status bar
2) Click the "Back" button in the browser
3) Now you should either see the correct page, or a "Webpage has expired" page
4) If you see "Webpage has expired": click "Back" button on the browser, and re-run the report.

The Syslog application will set up a listener on UDP port 514 on the agent computer. On Linux computers, this port may be considered privileged, and the Longitude agent will not have access to it using a non-privileged account. To work around this, you can either configure the Syslog listener to use a different port (with port number > 1024), and configure your devices sending syslog messages to send messages on that port, or you can run the agent using a privileged account.

To set up the Longitude agent to use a privileged account, modify the Linux Longitude agent as follows:

If you would like to upgrade your Longitude Server, but you cannot download the upgrade patch (e.g. because the Longitude Server does not have access to the Internet, or a proxy server is preventing the download), you need to download the patch manually to the \Longitude\appman\download folder on the Longitude server, and then configure the Download URL to be the file path to the download directory, preceded by the word: "File:". For example:

For Management Console patches:
File:c:\Program Files\Longitude\appman\download\patch.jar

For Agent patches:

If you configure Heroix Longitude to use RSA Authentication , you will need to configure remote agents to allow connections from the Management Station by saving the Management Station's certificate file to the agents. Downloading the Management Station’s certificate using Internet Explorer will be unsuccessful if the Management Station is also configured to use HTTPS. In this case, trying to download the certificate results in an error like the following:

"Internet Explorer cannot download about.do?certificate=yes from
server.domain.net"

If you attempt to add the Windows application and receive an error referencing "Cannot parse system info" this means that Longitude encountered a problem while autodiscovering the properties of the server. To work around this problem:

1. Open the Longitude Web Interface.
2. Go to the Manage Longitude Properties function (Adminstration » Component Management » Manage Longitude Properties).
3. Under the Management Station folder, click on the Statistics Server component link.
4. In the resulting properties display, click on the Advanced button.

A known issue where the resources, such as images and JavaScript files, referenced in the html of the main Web UI JSP page are not loaded by Internet Explorer can be avoided by accessing the HTTPS site directly, rather than accessing the HTTP site and getting redirected to the HTTPS site. Access the HTTPS site directly at:
