Hi @Serhan,
At Panorama level, this command will get stats for all rules at summary level:
https://{{host}}/api?key={{key}}&type=op&cmd=<show><rule-hit-count><device-group><entry name='{{device-group-name}}'><pre-rulebase><entry name='security'><rules><all/></rules></entry></pre-rulebase></entry></device-group></rule-hit-count></show>
If you use a similar command for a specific rule, you can detailed stats including last-hit-timestamp:
https://{{host}}/api?key={{key}}&type=op&cmd=<show><rule-hit-count><device-group><entry name='{{device-group-name}}'><pre-rulebase><entry name='security'><rules><rule-name><entry name='{{rule-name}}'/></rule-name></rules></entry></pre-rulebase></entry></device-group></rule-hit-count></show>
Hope that helps.
