Many people have problem with this when they want to use the official Evernote php-sdk. The example generates this error on many systems.

Missing required oauth parameter "oauth_token"

The issue happens in OauthHandler.php in function getTemporaryCredentials. There you will find a curl request and if you debug it you will see that it returns an empty result.

$info = curl_getinfo($handle);
print_r($info);
print_r("raw: ".$raw);
die();

Add this parameter to the request and it will work

CURLOPT_SSL_VERIFYPEER => 0

This basically tells you that your PHP installation is missing the required cacert.pem file. So open your php.ini file and find this parameter

curl.cainfo = ""

Download the latest cacert.pem file from https://curl.haxx.se/docs/caextract.html. Copy it to a local folder, I use “C:\Program Files\PHP\extras\ssl” and update the parameter in your php.ini

curl.cainfo = "C:\Program Files\PHP\extras\ssl\cacert.pem"

Restart IIS and it will work. Don’t forget to remove the CURLOPT_SSL_VERIFYPEER value from your curl request.

This guide assumes you have already installed Tomcat Server 7/8. Tomcat offers a connector (mod_jk) but it’s very old and requires a lot of configuration. So I’ll explain how to install and configure the connector from Boncode that’s hosted on RiaForge. This specific example was for an installation of HP Service Manager running on Windows 2012 / IIS 8.5

Installation

Download the latest version from http://tomcatiis.riaforge.org
Extract the .zip-file to a temp folder (AJP13_v1026.zip)

Run “dotnetfx35setup.exe” if .NET 3.5 is not yet installed on the server.

Execute “Connector_Setup.exe”

Configuration

The installer has copied the binaries and configuration file to “C:\Windows”

Open the file “BonCodeAJP13.settings” and modify the content as below. Feel free to change the path to LogFiles.

<Settings>
  <Port>8009</Port>
  <Server>localhost</Server>   
  <MaxConnections>200</MaxConnections>
  <LogLevel>1</LogLevel>  
  <FlushThreshold>0</FlushThreshold>
  <EnableRemoteAdmin>False</EnableRemoteAdmin>
  <LogDir>E:\LogFiles\APPLogs\BoncodeAJP</LogDir>
  <EnableHTTPStatusCodes>True</EnableHTTPStatusCodes>
</Settings>

Make sure the IIS Application Pool user has write access on the LogDir folder!
A folder named “BIN” has been created in the root of your website. It will be empty so copy these 2 files in it:

• C:\Windows\BonCodeAJP13.dll
• C:\Windows\BonCodeIIS.dll

Now we need to tell IIS which folders we want to forward to Tomcat. For HPSM this will be “smsso”. Create a new folder in the root of the website named “smsso”

Copy the “BIN” folder in “smsso”

Now add a handler mapping in IIS. Go to the subfolder named “smsso” and add a new managed handler.

Request path: *
Type: [select BonCodeIIS…. from the dropdown]
Name: BonCodeAll

Run “iisreset” to reload the settings file

Not everyone uses Google Analytics or other 3th party logfile parsers. So a customer asked me to create some reports based on their IIS logfiles. The web is full with examples so one more or less won’t make a difference 🙂

First step is to download Logparser v2.2 and install this on a PC. Doesn’t have to be the server. Default installation path is “C:Program FilesLog Parser 2.2”
Queries can be run from the command line or used via an external .sql-file. I prefer the latter method so I create 3 subfolders: “SQL”, “Logs”  & “Results”. I copied the IIS logfiles to subfolders under LOGS.

Mike Lichtenberg has a demo page with 50-examples to give you an idea what’s possible. Below are 2 simple examples that my customer wanted to have.

1. number of hits per day

Customer (internal webservice) has no stats tool so he wanted to know how many hits this WebService received over a period of time. The query is below, I will explain it afterwards. Save this query in a text-file and name it “RequestPerDay.sql”

SELECT QUANTIZE(TO_TIMESTAMP(date, time), 86400) AS Day, COUNT(*) AS Total
FROM Logs%cFolder%u_ex*.log where cs-uri-stem not like '/loadbalancetestpage.html' GROUP BY Day ORDER BY Day

What we do above is convert the date/time to a timestamp and group them by day (86400). If you replace 86400 by 3600 then you would receive stats per hour but the customer wanted to compare 6 months so we would have received too much output. Notice the ‘%cFolder%’ variable, I do this because there are numerous webservices and this way I can easily target a different subfolder. I also exclude a test-page that it is used by the hardware loadbalancer. Running this straight from the command line would be like this, notice how I pass the folder variable!

Logparser file:sqlRequestPerDay.sql?cFolder=N1-B

It works but not very handy so luckily LogParser supports other methods. Like CSV-export, don’t we all love that! Let’s try the command above again with some extra parameters.

Logparser file:sqlRequestPerDay.sql?cFolder=N1-B -stats:off -o:CSV > results/CSV/ReqPerDay.csv

So, nicely formatted and we can now use this data to create graphs in Excel or in any other tool that supports CSV-data.

2. Hits for a specific page

You know now how it works so we skip the blabla and go straight to the query and the output.

SELECT TO_TIMESTAMP(date, time) AS Day, cs-method as Method,
STRCAT( cs-uri-stem,
REPLACE_IF_NOT_NULL(cs-uri-query, STRCAT('?',cs-uri-query))
) AS Request,
STRCAT( TO_STRING(sc-status),
STRCAT( '.',
COALESCE(TO_STRING(sc-substatus), '?' )
)
) AS Status,
time-taken
FROM Logs%cFolder%u_ex*.log where cs-uri-stem like '/Pages/dymmyname.aspx' ORDER BY Day

Above we are grouping the url and also the status. The advantage is that you would see 401.3 instead of just error 401

Logparser file:sqlBO-Pickup.sql?cFolder=N1-B -stats:off -o:CSV > resultscsvBO-Pickup.csv

The possibilitied are endless so go ahead and try some queries on your own!!
