Need help on CLI command to fetch < VIP Name + current connections >
Hello Experts , I need help in modifying below command which should also give me information of VIP name along with current connection . show ltm virtual recursive all | grep 'Availability\|Current Connections' As you can see this command only gives info of current connection but it will not tell which VIP has the current connection value ... blue.whale@(F5-BIGIP-ACT)(cfg-sync In Sync)(Active)(/Common)(tmos)# show ltm virtual recursive all | grep 'Availability\|Current Connections' Display all 1942 items? (y/n) y Availability : available Current Connections 0 0 - Availability : available Current Connections 38 0 - Availability : available Current Connections 0 0 - Availability : available Current Connections 73 0 - Availability : available Current Connections 0 0 - Availability : available Current Connections 0 0 -Solved53Views0likes1CommentCreating a tmsh script with iControl REST and using it to restart HTTPD
Problem this snippet solves: TMSH has the ability to create tcl scripts that can be used to run multiple commands and transactions. It is rare that you will want to create on with TMSH but there are a few cases where this may be desirable. One of these is to restart HTTPD, which is difficult to do from iControl REST because the REST API is running over HTTPD and the restart will not be clean. See K13292945. This Python script creates a tmsh script, and then runs it to restart HTTPD. How to use this snippet: Syntax is <program_name.py> host user password Sample output: ./rest_script_example.py10.155.117.12 admin admin Before httpd (pid 3186) is running... After httpd (pid 3289) is running...
