My Cacti has wrong downtime problem about Monitor Plugin, please see the attachment.
After tracing plugins/monitor/monitor.php, i found the downtime is calculated by monitor_print_host_downtime function with $row['status_fail_date'] arguments.
$row['status_fail_date'] is captured from host table in database,the default value is "0000-00-00 00:00:00". Then, i check the lib/functions.php, $row['status_fail_date'] is updated by update_host_status function.
this is code snippet of update_host_status function.
if ($status == HOST_DOWN) {
.....skip....
if ($hosts[$host_id]["status"] == HOST_UP) {
/* increment the event failure count */
$hosts[$host_id]["status_event_count"]++;
/* if it's time to issue an error message, indicate so */
if ($hosts[$host_id]["status_event_count"] >= $ping_failure_count) {
/* host is now down, flag it that way */
$hosts[$host_id]["status"] = HOST_DOWN;
$issue_log_message = true;
/* update the failure date only if the failure count is 1 */
if ($ping_failure_count == 1) {
$hosts[$host_id]["status_fail_date"] = date("Y-m-d H:i:s");
}
/* host is down, but not ready to issue log message */
} else {
/* host down for the first time, set event date */
if ($hosts[$host_id]["status_event_count"] == 1) {
$hosts[$host_id]["status_fail_date"] = date("Y-m-d H:i:s");
}
}
}
My problem is why $hosts[$host_id]["status_fail_date"] is only updated when $ping_failure_count equals to 1. Can i remove the if-else statement?
Sorry for my bad english
Thanks for any help!!!
