Hi,
I use influxdb to monitor VPN access. A record is generated at each login / logout of an user. I get the following result in influxdb:
select * from vpn
name: vpn
time Id Type etat host ip user
1538430263718995024 53 win7 connexion 192.168.165.1 78.221.56.59 jdupont
1538434238902469237 53 win7 deconnexion 192.168.165.1 78.221.56.59 jdupont
Now I want to create a continuous query that measures the time between login and logout. I tried this:
SELECT elapsed("ip",1s) as "duration" from un_jour.vpn group by "user","Id"
Return :
tags: connId=53, user=jdupont
time duration
---- --------
1538434238902469237 3975
When I create continuous query with the same query like this :
create continuous query duration_cq_1h ON vpn BEGIN SELECT elapsed("ip",1s) as "duration" INTO "un_an" from "un_jour" group by time(1h),"user","Id","Type","host" END
They do nothing and return an error in logfile:
aggregate function required inside the call to elapsed
Can someone help me?
Thanks.
