Hi, I lost my ns-query benchmark today, I can not have my query latency : ```auto # asloglatency -N ns -h query Histogram : {ns}-query Log : /var/log/aerospike/aerospike.log From : 2018-11-08 15:34:39 can't find histogram query from start time tail ``` ```auto # asinfo -h localhost -v 'latency:' -l {ns}-read:12:31:44-GMT,ops/sec,>1ms,>8ms,>64ms 12:31:54,267610.3,0.00,0.00,0.00 {ns}-write:12:31:44-GMT,ops/sec,>1ms,>8ms,>64ms 12:31:54,20798.4,0.00,0.00,0.00 error-no-data-yet-or-back-too-small error-no-data-yet-or-back-too-small ``` It s strange I did not change anything recently… I try to re enable it but it still does not work ☹ ```auto # asinfo -v 'set-config:context=namespace;id=ns;enable-benchmarks-read=true' ok ``` ---

The read, write, and query (as well as udf, proxy, and re-repl) histograms are macro level histograms that are always ‘enabled’; however, if there haven’t been any data points collected for a particular macro level histogram, it will be omitted from the logs. By enabling ‘enable-benchmarks-read’, you have enabled microbenchmarks for read transactions. You can find more information about the servers benchmarks here: [https://www.aerospike.com/docs/operations/monitor/latency/index.html](https://www.aerospike.com/docs/operations/monitor/latency/index.html). Histograms are only maintained during the life of the Aerospike server process, if you restarted Aerospike, then you will need to allow the histogram to allow ~20 seconds for the histograms to accumulate data. ---

Thank you for your reply, much appreciated, I’m still discovering Aerospike. After restarting Aero server and waiting 30min, I still don’t have any query latency: ``` error-no-data-yet-or-back-too-small ``` It’s strange, because I have lots of operations running and my namespace write and read op/s are good. I m using Aerospike 3.14.1.2 Should I check something else? Thanks ---

Are you performing any queries? If not then there will not be any data. ```auto asadm -e "show stat like query_reqs" ``` Here, queries do not refer to regular gets/puts, they refer to lookups on a [secondary index](https://www.aerospike.com/docs/architecture/secondary-index.html). ---

Yes, ``` asadm -e "show stat query_reqs" .... query_reqs : 6920979 objects : 32109698 ``` . etc… I notice this in my aero log, don’t know if it is related : ``` Nov 09 2018 09:44:53 GMT: WARNING (particle): (particle_list.c:1954) OP_LIST_GET_RANGE: index 0 out of bounds for ele_count 0 Nov 09 2018 09:44:53 GMT: WARNING (rw): (read.c:400) {ns} read_local: failed as_bin_cdt_read_from_client() <Digest>:0x975560e9f93076dcbf5f7a029be21fdb5f7078c8 ``` ---

Sorry my asadm command was missing a “like” keyword. Well clearly you have been issuing queries, assuming they weren’t all failing: ```auto asadm -e "show stat like query_fail query_reqs" ``` If you are issuing queries and they are completing successfully, I see no reason from the code’s perspective that the histogram wouldn’t be logged (unless you have changed your `ticker-interval` to be disabled or very largs). ```auto asadm -e "show config like ticker" ```
