Web Monitoring - Get button field for login step

[Krapoto]

Hi everybody,

I'm trying to configure a web monitoring for a website on Zabbix 4.2.4.

The first step which consist of checking the web access is OK but I have a problem on my second step : Check Login.

I'm unable to identify the Post field for the "button Login".

The html Code part is the following :

<button id="bouton2" type="text" onclick="getElementById('loginform').submit()" onfocus="BoutonFocus('bouton2');" onblur="BoutonBlur('bouton2');" class="bouton">
                                    Connexion                                    <!-- <table border="0" cellpadding="0" cellspacing="0" onmouseover="BoutonFocus('bouton2');" onmouseout="BoutonBlur('bouton2');">
                                        <tr>
                                            <td><img src="/img/butleft.gif" id="bouton2left"></td>
                                            <td id="bouton2center" class="boutoncenter">Connexion</td>
                                            <td><img src="/img/butright.gif" id="bouton2right"></td>
                                        </tr>
                                    </table> -->
                                </button>

Can someone help me to understand where is the value that I have to get in this Html block because I don't see any "name field" ?

Thanks a lot !
