Zabbix web scenario monitor upload image

[[email protected]]

Dear all,

Just wonder how I could monitor the website upload image(s) speed.

Basically I have done curl upload part, like this:

$ curl -F "filecomment=Darth_Vadar file" -F "image=@/Users/admin/Downloads/Darth_Vadar_4096x3072.jpg" http://www.example.com/Uploader/upload_image.aspx

{"ID":"A66527F9501601FC76528F6D2994EF780718672A"," Exp":"jpg","Owner":"","Path":"http://www.example.com/AttachFiles/UserPhoto/temp","Width":4096,"Height":3072}

$

Now I go to Configuration -> Web -> Web scenarios -> (my own test scenarios) -> Steps -> Add:

Name: TEST_IMAGE
URL: http://www.example.com/Uploader/upload_image.aspx
Post: ??? <- What should I put here?
Timeout: 15
Required String: {"ID".*}
Required status codes: 200

Or is there any other way to do so?

Thanks.

Ming

Interesting question :-)

I'm not sure, but you can try this Post value:

filecomment=Darth_Vadar&name=@/<absolute_path>/Darth_Vadar_4096x3072.jpg;type=image/jpeg

And don't forget upload file Darth_Vadar_4096x3072.jpg with reading permissions for Zabbix to <absolute_path> on your Zabbix server.

Let me know your result.

@jan:

Thanks for swift reply.

I've tried your suggestion, but result message:

Error: Required pattern not found

I put:

Name: Test upload huge image
URL: http://www.example.com/Uploader/upload_image.aspx
Post: filecomment=Darth_Vadar_XL&name=@/tmp/darth-vader.jpg;type=image/jpeg
Timeout: 60 secs
Required string: {\"ID\".*}
Required status codes: 200

BTW, my scenario is set to 120 secs.

Although it came out some graphics in Monitoring -> Web -> (My scenariso).

Just wonder where should I look into to debug the upload process. Is there any log file for this?

[jan.garaj]

Required pattern not found: Your required string was not matched. It's a feature :-) Use only "ID" (without quotation marks and wildcard chars like *) - only "ID".

If you have a problem (I expect it, from Zabbix end :-D) please enable DebugLevel=4 in your Zabbix server config, restart server and post related debug lines from your Zabbix server log file.

Zabbix log files are in:
/var/log/zabbix
or
/tmp

Sorry guy, it doesn't work. I've test it in my test environment with last Zabbix version. I checked it also in source code httptest.c.

Zabbix sends form always with header application/x-www-form-urlencoded, when you send file with @.
Correct header is multipart/form-data. Also file is sended as raw string, not a binary file

My final answer: Zabbix is not able to handle web check for file uploading with standard Zabbix web check functionality at the moment - I recommend you to build some custom script in CLI

@jan,

Thanks a lot. At least I know I should head on the bash script way.
