    HPE iLO by HTTP : Error: maximum count of HttpRequest objects was reached

    Hi All,

    I'm trying to use the HPE iLo by HTTP but without any luck. This template was a Zabbix feature request, see [ZBXNEXT-8522] HPE iLo 5 by HTTP - ZABBIX SUPPORT
    I thought the template would work out of the box but it seems not. I have no idea what i'm doing wrong here?​

    The Zabbix version i'm running is 6.4.10
    The iLo version is 2.95 (iLo 5 on a DL380 Gen10)

    Regarding to the readme, an iLo user zbx_monitor with the ReadOnly role was created

    In Zabbix i created a new host with the HPE iLO by HTTP linked template.
    The host has 3 macro's set:
    ILO.URL which has value https://192.168.1.205
    ILO.USER which has value zbx_monitor
    ILO.PASSWORD which has the password of the zbx_monitor user

    In the iLO session list i can see the zbx_monitor has an active session
    In the iLO Event Log i can see the zbx_monitor user has Browser login / Browser logout activity

    When i check the discovery rules on the created host. The info label is showing an error message for each discovery rule:

    Preprocessing failed for: {"error":"Error: maximum count of HttpRequest objects was reached."}
    1. Failed: TypeError: cannot read property 'map' of undefined
    at [anon] (duktape.c:59387) internal
    at [anon] (function:3) preventsyield    ​

      Rebooting the whole server fixed the issue.

          Hi,
          Template does not work out of the box, because it have bugs out of the box .
          I guess after some time of you will need to reboot server again as template code unable to logout from ilo and session count is growing .
          I pointed these bugs to Zabbix support, but nobody cares.
          See my issue and I hope you will find how to fix template yourself.

              Below what needs to be changed in template at least :
              'Get Data' item code have bugs:

              In apiLogout function lines should be changed ( changed line starts with comment)

              1. from:
              url = encodeURI(ilo.session_url);


              to:
              url = encodeURI(ilo.params.ilo_url.replace(/\/$/, "") + ilo.session_url);
              ​

                  Thank you Audriusas.
                  So far no growing sessions with the original code.. I'll keep an eye on it.

                      It seems the discovery rules show a different error message with the apiLogout fix:
                      The user has a readonly profile.
