Web scenarios execution info required

[vinayak.mdesai]

Hi all,


If I create 10 scenarios of web monitoring, will they execute in parallel or sequential?


Thanks in advance

It depends.

A single poller loops sequencially through all scenarios where 'nextcheck' value is lower or euqal current time.

In case there are multiple http pollers configured, there is a chance that scenarios get executed at the same time by different pollers (e.g. scenarios with same 'nextcheck' values).
Scenarios are evenly distrubuted over multiple pollers similar to this example:

zabbix=# SELECT httptestid, MOD(httptestid,4) AS poller_id FROM httptest LIMIT 10;
 httptestid | poller_id
------------+-----------
         23 |         3
         17 |         1
         20 |         0
         16 |         0
         18 |         2
         19 |         3
         22 |         2
         21 |         1
          9 |         1
          7 |         3
(10 rows)
