    History of problems

    For how much time zabbix keep the record of a problem?
    I'm trying to search for problems for hosts, but i only found 'active' problems.
    When problems are solved they are deleted?...

  • Agent don't send value for newly created item in template

    Active agents, monitored through proxies, with auto registration enabled. When the agents are registered they are included in a group and linked to one template. The existing items are working seamless, but if i create a new item the agent don't send values for it. If i use zabbix_get on the proxy the...

  • Nunca fiz, mas quanto ao modem em si o que você pode fazer é procurar descobrir o modelo e ver no site dos fabricantes se (e quais) OIDs SNMPs estão disponíveis, usando posteriormente estas variáveis para monitorar o dispositivo.
    Algo factível também é usar um roteador com openwrt como...

    The error message you posted indicated that The agent is having a problema to access a file (the file is being used by another process), the agent don't need access to files to get CPU items, but it can getting stucked because of another item.
    Also the filename in the message seems strange (slashes...

  • The performance always depend on how many items are you monitoring. But for the 'average' scenario it's worth to separate the DB and use a connection poll (i myself use pgbouncer).
    Also it's probable that you need to use proxies (again it depends on how many items are you monitoring), IN MY SCENARIO,...

  • The load on the server will depend of how many items are you monitoring...
    Except if you have very few items i advise you to have one (or more, depending of how many items) proxy(ies)
    In my experience (7000+ hosts, 100 itens in each host) the only downside in the active agent are some situations...

  • Não conheço o ubiquiti, mas você está monitorando ele com agente?

    Se estiver por padrão o agente roda como usuário zabbix, se for assim bastaria dar acesso ao usuário zabbix para executar o comando reboot.
    Provavelmente você vai precisar monitorar o item, criar um trigger...

  • Você está criando este item onde?
    Em geral a fórmula para o last é diferente:
    Para item de host:
    {net.if.in[eth0].last()}+{net.if.in[eth1].last()}

    Para item de template:
    {nome_template:net.if.in[eth0].last()}+{nome_template:net.if.in[eth1].last()}

    Zabbix agent dying

    I have a zabbix server, configured with proxies and monitoring about 100+ hosts.

    Each day (or night) 4 to 5 agents stop working, the log don't show anything suspicious (currently in level 4).
    If i manually restart the agent, everything work fine (until it die again another day)....

  • I can't understand what you called 'same version', there is just one zabbix server, the packages that i need to look at are the ones of the installed on the hosts.

    There is just one correct version for each package,the trigger should be fired when the item gets a value that is different...
