FAQ: What are the ArcIMS Spatial Server log files?

Question

What are the ArcIMS Spatial Server log files?

Answer

The ArcIMS Spatial Server LOG files, located at <ArcIMS Installation Directory>/server/log on Windows and at <ArcIMS Installation Directory>/log on Linux/UNIX, store information about the work being performed by the various components of the Spatial Server. The LOG files are created each time the ArcIMS Monitor process is started and can be used to troubleshoot issues with the site. The level of information contained within the files depends on the logging mode specified. For details on the modes available, see the link in Related Information below.

In a typical installation, a total of eight (version 3.x) or nine (version 4.x) LOG files are created each time the ArcIMS Monitor process is started. Each component of the ArcIMS Spatial Server--image, query, feature, geocode, extract, and metadata (4.x only)--has its own LOG file. In addition, two LOG files are created for third party applications and one LOG file describes the overall state of the Spatial Server. Optional extensions and multiple Spatial Servers add to the total number of LOG files.

The LOG files are:

1. <Server machine name>_<Server id number>_<assigned number>.log
This contains information about threads used by the ArcIMS Spatial Server, including when each server (query, image, extract, feature, or image) is started and whether threads were successfully started.

Note:
From ArcIMS 9.2 this log file is named as <Server machine name>_<assigned number>_Container_<processid>.log

2. stderr_<server machine name>_<assigned number>.log
This contains error messages from third party applications used by the ArcIMS Spatial Server. This .log rarely has entries.

Note:
From ArcIMS 9.2 this LOG file is named as <Server machine name>_<assigned number>_stderr_<processid>.log

3. stdout_<server machine name>_<assigned number>.log
This contains informational messages from third party applications used by the ArcIMS Spatial Server. This .log rarely has entries.

Note:
From ArcIMS 9.2 this LOG file is named as <Server machine name>_<assigned number>_stdout_<processid>.log

4. QueryServer_<server machine>_<assigned number>.log
This contains a detailed description of the query services used by ArcIMS. This description includes thread initialization information, map configuration file content, requests, and responses. Performance information for requests and responses is kept in this file.

5. FeatureServer_<server machine>_<assigned number>.log
This contains a detailed description of features being accessed by the ArcIMS Spatial Server.

6. ImageServer_<server machine>_<assigned number>.log
This contains a detailed description of Image Services used by ArcIMS. This description includes thread initialization information, map configuration file content, requests, and responses. Performance information for requests and responses is kept in this file.

7. GeocodeServer_<server machine>_<assigned number>.log
This contains the requests and responses used when an address is located. The information included is the location of geocode stylesheets, the match key name, the location to be matched, and the time taken to perform the match.

8. ExtractServer_<server machine>_<assigned number>.log
This contains statistics on how long the ArcIMS Spatial Server took to access the features (search time) and how long it took to download the features to the client (retrieval time).

9. MetadataServer_<server machine>_<assigned number>.log (v4.x only)
This file contains a detailed description of Metadata Services used by ArcIMS. This description includes thread initialization information, requests, and responses. Performance information for requests and responses is kept in this file.

Note:
A LOG file with a prefix of "MetadataServer" is created only after the first Metadata Service has been started.


10. ArcMapServer_<server machine>_<assigned number>.log (v4.x only)
This file contains a detailed description of ArcMap Image Services used by ArcIMS. This description includes thread initialization information, configuration file content, requests, and responses. Performance information for requests and responses is kept in this file.

Note:
From ArcIMS 9.2 all virtual server LOG files are named in the format <Server Machine>_<assigned Number>_<ServerType>_<processid>.log

For example the Image server LOGs will be named as <Server Machine>_<assigned Number>_ImageServer_<processid>.log
