My zabbix setup is:
There are about 50 web scenarios , update interval of each web scenario is 30s ,
attempt is 2 , timeout of the web step check is 20s (only one step).
Trigger is `{Check WebURL:web.test.fail[{$WEBURL}].count(#2,1,eq)}=2`
Zabbix server is a VM with 32cores , 16G mem , SSD(cache)+HDD
The target web server and zabbix server are in the same LAN ,but differnet subnet(CIDR) .
Sometime(once a few days) , a web scenario will fail with error:
But in fact , the web server did response to zabbix server : (IIS log)
It is weird that why zabbix server did not get the http response .
Ubuntu 16.04 , zabbix is installed via apt-get ,
zabbix server version is 4.2.4.
curl 7.47.0 (x86_64-pc-linux-gnu) libcurl/7.47.0 GnuTLS/3.4.10 zlib/1.2.8 libidn/1.32 librtmp/2.3
