+# DNS bind statistics
+
+## Overview
+
+**Requirements**  
+
+Instead xml2 command, which was used in previous template version and unfortunately is not present at EL8 and newer RHEL based systems this template uses jq command and parses directly Json output of Bind statistic-channels. Added more values, Graphs and Dashboard.
+
+ Bind Server 9 and above  
+ Zabbix Server 4+ and above  
+ Zabbix Agent on monitored host
+ Installed jq and curl utility 
+
+
+**How it works**  
+Include statistics in named.conf  
+
+/etc/named.conf
+
+statistics-channels {
+	inet 127.0.0.1 port 8053 allow { 127.0.0.1; };
+};
+
+
+semanage port --add -t dns_port_t -p tcp 8053
+systemctl restart named
+dnf install jq curl
+
+Include - zabbix\_agentd.d/bind_jq.conf 
+UserParameter=bind.queries.jq[*],curl $3 2>/dev/null | jq ".$1.$2"
