NimbostratusIs There a "Key" to Rewriting TMSH Commands as RESTful Calls? +Example
Hiya,
I'm running this command remotely to get a pool member's active connections, but it's a) awfully kludgy and b) I'd like get the results from the RESTful API:
ssh $ID@$F5_HOST "show /ltm pool $POOL members { $POOL_MEMBER } default" | awk '/| Current Connections/ {print $(NF-1)}'
Awk grabs this line and returns the "ServerSide" stats for that pool:
| Current Connections 0 -
I've had some luck constructing URIs to pass into cURL from other TMSH commands, but I haven't really figured out a pattern I can follow to create arbitrary API requests. Do any of you have a handy trick or rule to follow?
Worst case, how the heck can I pull specific Traffic and Connection Queue statistics for pools and pool members via the API? Thanks?
Greetings, I've had good luck using most of the Rest API by simply appending "stats" to the end of a query. I'm by not means an expert here, but I do use Rest quite often due to its simplicity:
So I would grab the stats for a pool named "default_gw" using the following:
curl -sk -u admin:admin https://172.24.64.39/mgmt/tm/ltm/pool/~Common~default_gw/members/~Common~10.12.23.27:0/statsThe output would be similar to:
"generation":1 "selfLink":"https://localhost/mgmt/tm/ltm/pool/~Common~default_gw/members/~Common~10.12.23.27:0/stats?ver=12.0.0" "entries":{"https://localhost/mgmt/tm/ltm/pool/~Common~default_gw/members/~Common~10.12.23.27:0/~Common~10.12.23.27:0/stats":{"nestedStats":{"kind":"tm:ltm:pool:members:membersstats" "selfLink":"https://localhost/mgmt/tm/ltm/pool/~Common~default_gw/members/~Common~10.12.23.27:0/~Common~10.12.23.27:0/stats?ver=12.0.0" "entries":{"addr":{"description":"10.12.23.27"} "connq.ageEdm":{"value":0} "connq.ageEma":{"value":0} "connq.ageHead":{"value":0} "connq.ageMax":{"value":0} "connq.depth":{"value":0} "connq.serviced":{"value":0} "curSessions":{"value":0} "monitorRule":{"description":"/Common/gateway_icmp (pool monitor)"} "monitorStatus":{"description":"up"} "nodeName":{"description":"/Common/10.12.23.27"} "poolName":{"description":"/Common/default_gw"} "port":{"value":0} "serverside.bitsIn":{"value":175344} "serverside.bitsOut":{"value":215808} "serverside.curConns":{"value":0} "serverside.maxConns":{"value":10} "serverside.pktsIn":{"value":334} "serverside.pktsOut":{"value":240} "serverside.totConns":{"value":94} "sessionStatus":{"description":"enabled"} "status.availabilityState":{"description":"available"} "status.enabledState":{"description":"enabled"} "status.statusReason":{"description":"Pool member is available"} "totRequests":{"value":0}}}}}}
syncretismStats! I knew I had that somewhere in my notes. This is great - I'm passing the JSON object to jq and watching the number of connections in my script. Just what I needed. Thanks so much!
I was equally happy at discovering this one =) You're very welcome, glad this was helpful!
