Verify if TMSH command for monitor SEND and RECEIVE string is correct

Hi,

 

Can you guys check if my command is correct especially the SEND and RECEIVE string part:

 

tmsh create ltm monitor https NEW_HTTPS_MONITOR { defaults-from https destination : send "GET /wfc/applications/suitenav/navigation.do\r\n" recv "200 OK" }

 

This is the curl result on the server:

 

[root@USZYC-LB-INT-01:Active:In Sync] config curl -ik https://1.1.1.1/wfc/applications/suitenav/navigation.do HTTP/1.1 200 OK Cache-Control: no-cache Pragma: no-cache Content-Length: 1405 Content-Type: text/html;charset=utf-8 Content-Language: en Server: Microsoft-IIS/7.5 X-Powered-By: Servlet 2.4; JBoss-4.3.0.GA_CP01 (build: SVNTag=JBPAPP_4_3_0_GA_CP01 date=200804211657)/Tomcat-5.5 Set-Cookie: JSESSIONID=ACC363DD9F599A02F9E983F3F61D94C3; Path=/wfc; Secure X-Powered-By: ASP.NET Date: Tue, 06 Nov 2018 00:25:00 GMT

    I dont see any issues, but use this below if you feel its fine,

    • you need not specify defaults-from https, because its a https is the default parameter, unless you want someother custom parent to be used, then use the defaults-from.

    • Same applies for the destination, ":" is the default value.

    tmsh create ltm monitor https NEW_HTTPS_MONITOR { send "GET /wfc/applications/suitenav/navigation.do HTTP/1.1\\r\\nUser-Agent: BigIP\\r\\nHost: applicationname.com\\r\\nConnection: close\\r\\n\\r\\n" "200 OK"}

    How about the intervals and timeout, are you going with the default values.

    Edit: Hey sorry I just noticed there's no HTTP Version ( HTTP/1.0 or HTTP/1.1) in your send string, so if you go with your original send request, it will fail.

    If you are going with HTTP/1.0, you need not have other HTTP headers like host close agent etc.
