how to capture the last request ID

[#1]

how to capture the last request ID from API , in order to trace the status ( as IN_PROCESS )

for example we run some API to restart a service , then I want to run API that will capture the last request ID

example of request "id"

{ "href" : "http://192.23.45.2.ur.com:8080/api/v1/clusters/HDP01/requests/17",

"Requests" : { "id" : 17,

"status" : "Accepted" }

To list all the requests use the following API and see what is the maximum request ID (which will be the recent one, Higher the requestID more recent one it is):

# curl -sH "X-Requested-By: ambari" -u admin:admin -i http://localhost:8080/api/v1/clusters/Sandbox/requests?fields=Requests/request_status | grep -A 1 id | awk '{print $NF}' > /tmp/requests_details.txt;  sed -e '1,2d' -e s'/--//g'  -e 's/\n//g' -e 's/"//g' -e '/^$/d' /tmp/requests_details.txt | awk 'NR%2{printf "%s ",$0;next;}1' 

Example Output:

185, COMPLETED
186, COMPLETED
187, COMPLETED
188, FAILED
189, COMPLETED
190, COMPLETED
191, COMPLETED
193, COMPLETED
195, COMPLETED
196, COMPLETED
197, COMPLETED
198, COMPLETED
199, COMPLETED
200, COMPLETED
201, COMPLETED
202, COMPLETED
203, COMPLETED
204, COMPLETED
206, ABORTED

.

.

Then if you want to see only the IN_PROGRESS requests then you can make the following API call.

# curl -sH "X-Requested-By: ambari" -u admin:admin -i http://localhost:8080/api/v1/clusters/Sandbox/requests?fields=Requests/request_status | grep -A 1 id | awk '{print $NF}' > /tmp/requests_details.txt;  sed -e '1,2d' -e s'/--//g'  -e 's/\n//g' -e 's/"//g' -e '/^$/d' /tmp/requests_details.txt | awk 'NR%2{printf "%s ",$0;next;}1' | grep -i 'IN_PROGRESS' 

Example Output:

# curl -sH "X-Requested-By: ambari" -u admin:admin -i http://localhost:8080/api/v1/clusters/Sandbox/requests?fields=Requests/request_status | grep -A 1 id | awk '{print $NF}' > /tmp/requests_details.txt;  sed -e '1,2d' -e s'/--//g'  -e 's/\n//g' -e 's/"//g' -e '/^$/d' /tmp/requests_details.txt | awk 'NR%2{printf "%s ",$0;next;}1' | grep -i 'IN_PROGRESS' 

207, IN_PROGRESS
