Hi Asif,<br><br>I don't know of any specific applications or methods to stress test MapServer. However, I would think that you could use some web-based tools such as Selenium (possibly) to exercise a web-based setup, or write a test-script which does the same. Sean Gillies has an excellent set of unit tests written to exercise Python Mapscript. You can view them here - <a href="http://kentuckykarst.org/mapserver/mapscript/python/tests/cases/">http://kentuckykarst.org/mapserver/mapscript/python/tests/cases/</a>. It might be possible to adapt some of these to suit your needs, but I would think that a utility which exercises your installation in the same way a user does would be better.<br>
<br>There is a good, generic description of how to approach load testing of web applications here - <a href="http://msdn.microsoft.com/en-us/library/bb924374.aspx">http://msdn.microsoft.com/en-us/library/bb924374.aspx</a>.<br>

Hello,<br>
<div><br>
We have started using Map Server to serve large size images. Now we want to do a performance/stress test on Map Server. Do you have any documentation that explains the performance/stress test on a Map Server? If not, could you please suggest what shall I do?<br>

While it may be a bit of overhead to implement just for testing, the<br>
GeoMoose client would definitely help with your performance testing. If<br>
you combine it with FireBug/FireFox, you should be able to extract all<br>
the performance information you need (from the client end).<br>
<br>
>From the server side, you can run the MapServer requests on the<br>
commandline. In my experience though, the web side of the equation is<br>
usually the bottleneck for most performance issues.<br>

I have tiled a large mosaic(2 GB) by using the GDAL utility(gdal_convert<br>
"TILED=YES"). I want to test the performance for querying the mosaic<br>
with the zoom functionality. Do I need to write a client or is there<br>
anything readily available with which I can check the performance?<br>

Hi Asif,<br>
<br>
</div>My apologies. I saw your message Friday evening but forgot about it<br>
over the weekend in the course of reinstalling my Linux OS. If time is<br>
of the essence, posting your question to the entire list should ensure a<br>
speedier response.<br>
<br>
Regarding your questions:<br>
<br>
1) I am not aware of any applications that will act as viewers for<br>
Mapserver operating in "map" mode. They may exist, but I'm not familiar<br>
with them. I tend to use Mapserver in only one of two ways at the<br>
moment; in "map" mode to generate static maps, in "wms" mode with a<br>
connection to it via OpenLayers (or TileCache).<br>
<br>
2) Regarding the path to your mapfile, I believe there are several<br>
solutions that you can try if your goal is to shorten the URL string.<br>
They are well-explained here -<br>
<a href="http://mapserver.gis.umn.edu/docs/howto/wms_server/#more-about-the-online-resource-url" target="_blank">http://mapserver.gis.umn.edu/docs/howto/wms_server/#more-about-the-online-resource-url</a>.<br>
As far as why the 1st URL doesn't actually work, it's because the path<br>
should be relative to the mapserv.exe location in cgi-bin, not to<br>
htdocs. So try this instead:<br>
<br>
-<br>
<a href="http://localhost:9090/cgi-bin/mapserv.exe?map=../htdocs/mapdemo/itasca_demo.map&mode=map" target="_blank">http://localhost:9090/cgi-bin/mapserv.exe?map=../htdocs/mapdemo/itasca_demo.map&mode=map</a><br>

Hi All,<br>
<br>
<br>
<br>
I have couple of question, could you please take a look at it :<br>
<br>
<br>
<br>
1) Do you know any Map Server Client that allows viewing the image<br>
service (created on the Minnesota Map Server) if I give the URL listed<br>
below:<br>
<div><br>
<a href="http://localhost:9090/cgi-bin/mapserv.exe?map=/path/to/itasca.map&mode=map" target="_blank">http://localhost:9090/cgi-bin/mapserv.exe?map=/path/to/itasca.map&mode=map</a>"<br>
<br>
<br>
<br>
</div>2) I am using Windows XP on my PC. When I give the URL in this<br>
format -<br>
<a href="http://localhost:9090/cgi-bin/mapserv.exe?map=/mapdemo/itasca_demo.map&mode=map" target="_blank">http://localhost:9090/cgi-bin/mapserv.exe?map=/mapdemo/itasca_demo.map&mode=map</a>",<br>
it doesn't work. But if I give it in format -<br>
<div><a href="http://localhost:9090/cgi-bin/mapserv.exe?map=C" target="_blank">http://localhost:9090/cgi-bin/mapserv.exe?map=C</a>:\Asif\work\devtools\MMS\ms4w\Apache\htdocs\mapdemo\itasca_demo.map&mode=map<br>

, it works. The problem in giving the URL is this format is I have to<br>
put the complete path starting with "C: drive" and if I have to run it<br>
on the server, I cannot give it like that.<br>
<br>
<br>
<br>
Could you please help me with both the above issues? Thanks!<br>

Hi Asif,<br>
<br>
I downloaded the demo.tif file that you sent earlier, and the<br>
itasca_demo.map from you rprevious email. I changed the path in the<br>
DATA portion of the LAYER section to point to my filesystem,<br>
DATA "/var/www/mapfiles/itasca/demo.tif"<br>
<br>
</div>and also changed the EXTThis matches the extent of the file when you run gdalinfo against it<br>
<div>(min_x min_y max_x Max_y).<br>
<br>
With these changes, I'm able to view the file with the following URL:<br>
<a href="http://localhost/cgi-bin/mapserv?map=/var/www/mapfiles/itasca/itasca_demo.map&mode=map" target="_blank">http://localhost/cgi-bin/mapserv?map=/var/www/mapfiles/itasca/itasca_demo.map&mode=map</a><br>
<br>
(Note, I'm running this in Linux, so paths and URLs are going to be<br>
slightly different than yours)<br>
<br>
Try changing your EXTENT entry to match mine, that might do the trick.<br>

Hi Asif,<br>
<br>
Best thing to do is take a look at these 2 docs first:<br>
- <a href="http://mapserver.gis.umn.edu/docs/howto/raster_data" target="_blank">http://mapserver.gis.umn.edu/docs/howto/raster_data</a><br>
- <a href="http://tilecache.org/readme.html" target="_blank">http://tilecache.org/readme.html</a><br>
<br>
Once you have the ability to see your raster in MapServer via a<br>
"mode=map" request, then you will have to decide how you wish to view<br>
your data afterwards. There are different things to do in TileCache<br>
depending on whether you wish to view the data in OpenLayers, or over<br>
Google Maps/MS VE.<br>

You'll want to ask the TileCache list about that, likely. Once you have<br>
MapServer actually serving up the imagery, get your client using<br>
MapServer or WMS (I like OpenLayers, myself). Then install TileCache and<br>
change the OL app to use TC's URL instead of MapServer's. Easy.<br>
<br>
But you may want to install OpenLayers and get it working with MapServer<br>
first, then hit up the OL and TC mailing lists.<br>
