Почему в Grafana zabbix рванные графики?

Question

[KIRNESS]

Накинул на zabbix 5.0.3 grafana, раскидал графики, и в моменте вижу что они получаются какие то рванные.

В чем собственно может быть проблема ?

Может где в настройке графиков пункт какой то поставить надо ?

Answer 1

[ky0]

Судя по логам - у вас какие-то проблемы с сетевой связностью до хоста. Либо правда что-то с сетью, либо надо покурить настройки заббикс-сервера на предмет количества процессов-сборщиков, памяти и т. д.

Answer 2

[Saboteur]

Так это больше похоже, что чек не срабатывает регулярно, и не записывает в базу значение.
Судя по расписанию разрывов, у вас на 25 минуту может стоять, например, еще какой-то чек или другая акивность, из-за чего общая нагрузка вызывает таймаут у заббикса.

Хорошо, но как отладить этот разрыв то ?

[KIRNESS]

и как странно пока что из 20 объектов только на 1 такое

[Максим Гришин]

KIRNESS, сам заббикс-сервер не испытывает ли проблем с запуском мониторов или записью данных в базу? Если вдруг на 26й минуте имеется всплеск zabbix queue, смотрите, что загружает сам сервер. Посмотрите, не запускается ли по расписанию что-то на том хосте, с которым рвется связь. Посмотрите, нет ли у вас потерь на сети. Вообще такой график настраивает на вдумчивую отладку на месте, а не "по телефону".
