I have an idea.
Where you could use the results from calling SOAP method.
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<operationsErrorCount xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://TestServer/MonitoringWebService.tws">
</operationsErrorCount>
</soap:Body >
</soap:Envelope >
Where Results wound be.
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<operationsErrorCountResponse xmlns="http://TestServer/MonitoringWebService.tws">
<oCount>2</oCount>
</operationsErrorCountResponse>
</soapenv:Body>
</soapenv:Envelope>
The idea is to make results into graph where you also could make warning and critical depending on the response count.
