NextWordBoundary. • Logstash now sends the epoch value every 20 seconds to the logstash_heartbeat trapper item • You can use this to further process the data in Zabbix: • trigger when there is too much time between epoch values • trigger when you do not receive any values for a period of time 21. Basically, whenever Zabbix standard preprocessing options fall short, there is a good chance it can be done with Javascript preprocessing. Custom multiplier (1) Master Item update interval - 5 minutes In this configuration subprocess preprocessing manager using over 19Gb of memory in customer environment, and RAM is not freed after time Situation is reproduced in test environment (Zabbix-Proxy 4. Consider, you have one of these two datasets (or a part of it) downloaded in folder path/to/scans. transform_sample_counts(GP.
