Peter noticed that there were 5.2 million hits on CGSpace in 2019-10 according to the Atmire usage statistics
|
||
|
|
|
||
|
|
|
||
|
|
I looked in the nginx logs and see 4.6 million in the access logs, and 1.2 million in the API logs:
|
||
|
|
|
||
|
|
# zcat --force /var/log/nginx/*access.log.*.gz | grep -cE "[0-9]{1,2}/Oct/2019"
|
||
|
|
4671942
|
||
|
|
# zcat --force /var/log/nginx/{rest,oai,statistics}.log.*.gz | grep -cE "[0-9]{1,2}/Oct/2019"
|
||
|
|
1277694
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
So 4.6 million from XMLUI and another 1.2 million from API requests
|
||
|
|
|
||
|
|
Let’s see how many of the REST API requests were for bitstreams (because they are counted in Solr stats):
|
||
|
|
|
||
|
|
# zcat --force /var/log/nginx/rest.log.*.gz | grep -c -E "[0-9]{1,2}/Oct/2019"
|
||
|
|
1183456
|
||
|
|
# zcat --force /var/log/nginx/rest.log.*.gz | grep -E "[0-9]{1,2}/Oct/2019" | grep -c -E "/rest/bitstreams"
