Настройка пуллеров и долгий старт

[zverek06]

Собственно сабж, проблема со StartPollers, все время упирается в 100% и все тут.
1) Вот такая ситуация за сутки:

s019.radikal<.>ru/i632/1611/06/84467f8eef76.png

Не получается вставить картинку, ругается форум на ссылки. Завуалировал .ru ... (убрать в ссылке <>)
выручайте. вроде всего хватает, чего он упирается в 100% не пойму.. При чем то нормаль, нормально - раз и уперся... ставил StartPollers и 80 и 100 и сейчас 120 - ситуация та же

2) При старте или рестарте zabbix сервера происходит следующее:
Стартует без проблем, работает примерно минут 20-30, потом примерно около 40-50 минут заббикс не получает никакой информации, все графики идут пустые, после все нормализиуется и работает стабильно, без провалов в графиках. Почему такое может быть? Поэтому стараюсь как можно реще его "рестартовать". Мало того, что рестарт службы занимает минут 15, еще и такой провал потом...

А что с нагрузкой на железо в эти моменты (iops, например, cpu)?
Что застревает в очереди по утрам (см график Zabbix queue)?

А что с нагрузкой на железо в эти моменты (iops, например, cpu)?
Что застревает в очереди по утрам (см график Zabbix queue)?

+ сюда же:
1) ps auxf | grep zabb | grep poller - примерно покажет чем пуллеры в данный момент заняты
2) Включить логи и смотреть в момент проблемы

Скорей всего настроено снятие каких нить айтом, которые не могут сняться (например через userparametr "почему-то" не исполняются) или массово железки уходят в оффлайн, и все пуллеты затыкаются на этих железках.

В общем: колво неподдерживаемых айтемов свести к нулю, неотвечающих хостов тоже, после этого смотреть логи в момент проблемы (можно даже дебаг)
