 ====== Mailserver - Logfileauswertungen unter CentOS 7.x ======
 Oft werden vom Management hübsche bunte Auswertungsgraphiken gewünscht, um sich so mehr oder weniger ein Bild davon zu machen, ob und wie der/die Mailserver mit der anfallenden Menge an elektronischer Post umgehen können.
-Auch als Postmaster und Admin können wir uns so einen kurzen Überblick verschaffen, ob alles im //grünen Bereich// ist, ohne dazu extra langwierig im Logfile unseres Mailservers herumzusuchen. Hierzu stehen uns mehrere Hilfsprogramme zur Verfügung.

 Mailgraph besteht im wesentlichen aus zwei Teilen. Das eine perl-Script ist zuständig für das Durchsuchen und Analysieren des Mailserver-Logdatei. Die gewonnenen Daten werden in **rrd**-Datendateien geschrieben. Ein zweites Perl **cgi**-Script generiert dann beim Aufrufen der zugehörigen Webseite Graphiken mit den Daten der **rrd**-Dateien.

 So lassen sich z.B. auch die Reports zu **SPF**, **DKIM** und **DMARC** ausblenden, wenn man diese (aktuell noch) nicht haben möchte. Will man später die Graphen wieder sehen, reicht das Entfernen des Kommentarzeichens **#** am Anfang der betreffenden Zeilen.
+===== Mailgraph-NG für mehrere Mailserver =====
+Betreibt man mehrere Mailserver will man neben den Einzelstatistiken der einzelnen Mailserver oft auch einen Überblick über den gesamten Mail-Server-Verkehr haben.
+Auch das lässt sich mit einem überschaubaren Aufwand realisieren. Hierzu gehen wir wie folgt vor.
+  - Von den einzelnen Mailservern holen wir die RRD-Dateien ab.
+  - Diese kopieren wir dann auf ein zentrales Verzeichnis auf unserem WEB-Server.
+  - Wir passen unser CGI-Script, welches für die dynamische Generierung der WEB-Seite benutzt wird, soweit an, dass beim Erstellen eines Graphen nicht nur eine Datenquelle herangezogen wird, sondern die Summe unserer einzelnen Mailserver verwendet werden soll.
+Auf diese drei Schritte gehen wir nun im Detail noch ein.
+==== RRD-Dateien einsammeln ====
+Die einzelnen RRD-Dateien unserer Mailserver kopieren wir mit scp in ein temporäres Arbeitsverzeichnis unseres WEB-Servers. Hierzu legen wir uns erst einmal einen eigenen User an.
+   # groupadd -g 1100 mx-transfer && useradd -c "MX Transfer User" -d /home/mx-transfer -g 1100 -s /bin/bash -u 1100 mx-transfer
+<WRAP center round tip 80%>
+Das Gleiche machen wir auf jedem der MX-Hosts, von denen wir später die Dateien einsammeln möchten.
+</WRAP>
+Anschließend generieren wir uns einen ssh-key für diesen transfer-User. Hierzu schlüpfen wir erst in die Rolle dieses speziellen Users.
+   # su - mx-transfer
+Anschließend legen wir das Unterverzeichnis für den SSH-Schlüssel an und passen dessen Verzeichnisrechte an.
+   $ mkdir ~/.ssh
+   $ chmod 700 ~/.ssh
+<WRAP center round tip 80%>
+Auch hier legen wir auf jedem der MX-Hosts, von denen wir später die Dateien einsammeln möchten, das Verzeichnis mit den nötigen Berechtigungen an.
+</WRAP>
+Nun legen wir uns einen ssh-key ohne Passphrase an, in dem wir bei der Frage nach der Passphrase einfach keine angeben.
+   $ ssh-keygen -b 4096 -t rsa -C "MX Transfer User"
+<code>Generating public/private rsa key pair.
+Enter file in which to save the key (/home/mx-transfer/.ssh/id_rsa):
+Enter passphrase (empty for no passphrase):
+Enter same passphrase again:
+Your identification has been saved in /home/mx-transfer/.ssh/id_rsa.
+Your public key has been saved in /home/mx-transfer/.ssh/id_rsa.pub.
+The key fingerprint is:
+:9d:ab:8e:62:66:85:da:49:9e:29:75:60:23:a7:e2 MX Transfer User
+The key's randomart image is:
++--[ RSA 4096]----+
+|                 |
+|       . .       |
+|      o o        |
+|. =    o .       |
+| = +    S        |
+|o + o  .         |
+|o* *  .          |
+|oE@  o           |
+| = .. .          |
++-----------------+
+</code>
+Den public-key kopieren wir nun anschließend auf jeden unserer MX-Hosts.
+   $ ssh-copy-id -i ~/.ssh/id_rsa.pub mx11.dmz.nausch.org
+   $ ssh-copy-id -i ~/.ssh/id_rsa.pub mx12.dmz.nausch.org
+   $ ssh-copy-id -i ~/.ssh/id_rsa.pub mx13.dmz.nausch.org
+   $ ssh-copy-id -i ~/.ssh/id_rsa.pub mx14.dmz.nausch.org
+Als nächstes legen wir uns die temporären Zielverzeichnisse auf unserem Webserver an, in die wir später via scp die RRD-Dateien kopieren.
+   $ mkdir -p ~/mailgraph/{mx11,mx12,mx13,mx14}
+Somit haben wir folgende Verzeichnisstruktur auf unserem Server.
+<code>/home/mx-transfer/
+└── mailgraph
+    ├── mx11
+    ├── mx12
+    ├── mx13
+    └── mx14
+</code>
+Für das Einsammeln der RRD-Dateien legen wir uns ein passendes Script im Verzeichnis //**~/bin**// an. Fehlt dieses Verzeichnis, so legen wir zuvor dieses noch an.
+   $ mkdir ~/bin
+   $ vim ~/bin/mx-collect
+<file bash ~/bin/mx-collect>#!/bin/bash
+# Django : 2015-02-26
+# Einsammeln der RRD-Files von den einzelnen Mailservern
+cd /home/mx-transfer/mailgraph/mx11
+scp 10.100.0.87:/var/lib/queuegraph/mailqueues.rrd .
+scp 10.100.0.87:/var/lib/mailgraph/*.rrd .
+cd /home/mx-transfer/mailgraph/mx12
+scp 10.200.0.87:/var/lib/queuegraph/mailqueues.rrd .
+scp 10.200.0.87:/var/lib/mailgraph/*.rrd .
+cd /home/mx-transfer/mailgraph/mx13
+scp 10.300.0.87:/var/lib/queuegraph/mailqueues.rrd .
+scp 10.300.0.87:/var/lib/mailgraph/*.rrd .
+cd /home/mx-transfer/mailgraph/mx14
+scp 10.400.0.87:/var/lib/queuegraph/mailqueues.rrd .
+scp 10.400.0.87:/var/lib/mailgraph/*.rrd .
+</file>
+Damit das Script auch ausgeführt werden kann, geben wir ihm noch das entsprechende **x**-Recht.
+   $ chmod +x ~/bin/mx-collect
+Im 5-minütigen Abstand holen wird dann die Daten von den Mailservern ab. Hierzu nutzen wir die benutzerindividuelle **crontab** unseres Transfer-Users.
+   $ crontab -e
+<code># Django : 2015-02-26

+Nach kurzer Zeit haben wir nunmehr von den einzelnen Mailservern die Statistikdaten mit einer Aktualität von 5 Minuten vorliegen.

+==== Datenbereitstellung ====
+Das CGI-Script, welches wir zum dynamischen Generieren der Statistikgraphen verwenden, bekommt im Verzeichnis //**/var/lib/mailgraph/**// zur Verfügung gestellt. Für jeden unserer Mailserver legen wir dort ein Unterverzeichnis an.
+   # mkdir -p /var/lib/mailgraph/{mx11,mx12,mx13,mx14}
+Die Befüllung dieser Zeilverzeichnisse nehmen wir jeweils mit Hilfe eines **rsync**-Aufrufs vor, den wir via cronjob ausführen lassen.
+   # vim /etc/crontab
+<file bash /etc/crontab>SHELL=/bin/bash
+PATH=/sbin:/bin:/usr/sbin:/usr/bin

+Nach wenigen Minuten stehen die Statistikdaten, jeweils mit einer Aktualität von 5 Minuten, in den Zielverzeichnissen zur Verfügen, wo diese nun von dem CGI-Script eingelesen und aus den Daten die Graphen produziert werden können.
+==== Generierung Statistikgraphen und Webseite(n) ====
+Zur Präsentation unserer Statistikdaten benötigen wir nun noch einen Webserver, der die aufbereiteten Daten bereitstellt. Hierzu legen wir uns folgende Verzeichnisstruktur an.
+<code>/usr/share/mailgraph-ng/

+=== Unterprogramme graph_xxx - kumulierte Werte für die Generierung der RRD-Graphiken ===
+Bei der Generierung der kumulierten Graphiken stellt sich grundsätzlich die Frage, wie führt man den Inhalt mehrerer RRD-Dateien zusammen um einen Summengraph zu erstellen. Anstatt nun einen neue RRD-Datei mit dem Inhalt der vier einzelnen RRD-Dateien zu erstellen um daraus dann den Graphen zu generieren, wählen wir einen anderen Weg. Bei der Erstellung eines Summengraphen mit Hilfe von **RRD_GRAPH** bedienen wir uns nicht nur einer Quelle (RRD-Datei), sondern wir lassen **RRD_GRAPH** die Daten aus den einzelnen RRD-Dateien zusammenrechnen und erstellen dann den Graphen.
+Dazu müssen wir im ersten Schritt **alle Datenquellen** beim RRD_GRAPH Parameter **DEF** benennen. Somit wird z.B. beim Graphen mit den nicht angenommenen Nachrichten **Rejected** statt der **beiden Zeilen** <code>
+"DEF:rejected=$rrd:rejected:AVERAGE",
+"DEF:mrejected=$rrd:rejected:MAX",
+</code>
+entsprechend **acht Zeilen**
+<code>
+"DEF:rejected_11=$rrd_11:rejected:AVERAGE",
+"DEF:mrejected_11=$rrd_11:rejected:MAX",
+"DEF:rejected_12=$rrd_12:rejected:AVERAGE",
+"DEF:mrejected_12=$rrd_12:rejected:MAX",
+"DEF:rejected_13=$rrd_13:rejected:AVERAGE",
+"DEF:mrejected_13=$rrd_13:rejected:MAX",
+"DEF:rejected_14=$rrd_14:rejected:AVERAGE",
+"DEF:mrejected_14=$rrd_14:rejected:MAX",
+</code>
+Bei der Generierung der eigentlichen Graphen ziehen wir die **Summe der vier RRD-Dateien** heran, egal ob eine einfache Fläche, ein gestapelter Bereich oder ein Liniengraph erzeugt werden soll. Beim RRD_GRAPH Parameter **CDEF** lassen wir daher die Summe aus den Variablen //**rejected_11**//, //**rejected_12**//, //**rejected_13**// und //**rejected_14**// berechnen.
+Hierzu verwenden wir die //RRD_GRAPH eigene Berechnungssyntax// : ''∑ = %%((%%(A + B) + C) + D)''.
+Im Falle unseres Graphen über die Abgelehneten Nachrichten (**rejected**) berechnet sich die Gesamtsumme also wie folgt: \\ <code>∑ = (((rejected_11 + rejected_12) + rejected_13) + rejected_14)</code>
+Daraus wird dann in der //RRD_GRAPH eigenen Berechnungssyntax//:
+   ∑=rejected_11,rejected_12,+,rejected_13,+,rejected_14,+,
+Anstatt der ursprünglichen **CDEF**-Definitionen
+<code>
+"CDEF:rrejected=rejected,60,*",
+"CDEF:drejected=rejected,UN,0,rejected,IF,$step,*",
+"CDEF:rmrejected=mrejected,60,*",
+</code>
+verwenden wir also nachfolgende **CDEF**-Definitionen:
+<code>
+"CDEF:rrejected=rejected_11,rejected_12,+,rejected_13,+,rejected_14,+,60,*",
+"CDEF:drejected=rejected_11,rejected_12,+,rejected_13,+,rejected_14,+,UN,0,rejected_11,rejected_12,+,rejected_13,+,rejected_14,+,IF,$step,*",
+"CDEF:rmrejected=mrejected_11,mrejected_12,+,mrejected_13,+,mrejected_14,+,60,*",
+</code>
+Diese Änderungen tragen wir nun bei den Unterprogrammen **graph_xxx** nach.
+=== Unterprogramm print_html  ===
+Wie auch schon bei den [[centos:mail_c7:mta_13?&#cgi-scripte_fuer_die_einzelsysteme|Unterprogrammen print_html der Einzelsysteme]], erweitern wir nun noch das Unterprogramm **print_html** um die links zu den verweisenden Statistikseiten.

+==== Apache VHost anlegen ====
+Damit wir bequem von unserem Browser aus, die aktuellen Graphiken abfragen können, bearbeiten wir entweder die aus dem RPM stammende Konfigurationsdatei oder legen wir nun einen passenden VHost an.
+  # vim /etc/httpd/conf.d/vhosts.conf
+<file apache /etc/httpd/conf.d/vhosts.conf>
+#
+# mailgraph.nausch.org
+#
+<VirtualHost *:80>
+	ServerAdmin webmaster@nausch.org
+	ServerName mailgraph.nausch.org
+	ServerAlias www.mailgraph.nausch.org
+	ServerPath /
+	DocumentRoot "/usr/share/mailgraph-ng/mx"
+	AddHandler cgi-script .cgi
+	<Directory "/usr/share/mailgraph/mx">
+            AllowOverride None
+            Options +ExecCGI
+            DirectoryIndex mailgraph.cgi
+            require IP 10.0.
+	</Directory>
+	<Directory "/usr/share/mailgraph/mx11">
+            AllowOverride None
+            Options +ExecCGI
+            DirectoryIndex mailgraph.cgi
+            require IP 10.0.
+	</Directory>
+	<Directory "/usr/share/mailgraph/mx12">
+            AllowOverride None
+            Options +ExecCGI
+            DirectoryIndex mailgraph.cgi
+            require IP 10.0.
+	</Directory>
+	<Directory "/usr/share/mailgraph/mx13">
+            AllowOverride None
+            Options +ExecCGI
+            DirectoryIndex mailgraph.cgi
+            require IP 10.0.
+	</Directory
+	<Directory "/usr/share/mailgraph/mx14">
+            AllowOverride None
+            Options +ExecCGI
+            DirectoryIndex mailgraph.cgi
+            require IP 10.0.
+	</Directory
+	ErrorLog logs/mailgraph_error.log
+	CustomLog logs/mailgraph_access.log combined
+</VirtualHost>
+</file>
+Bevor wir bei unserem Webserver eine Reload der Konfiguration vornehmen, testen wir unsere neue Konfigurationsdatei auf syntaktische Fehler.
+   # apachectl -t
+   Syntax OK
+Da keine Fehler aufgetreten sind, aktivieren wir die neue Konfiguration durch einen Reload des Webserver-Daemon.
+   # systemctl reload postfix
+==== NGiNX vHost anlegen ====
+Nutzen wir als Webserver **[[centos:web_c7:nginx_1|NGiNX]]** können wir auch hier schnell und einfach einen passenden vHOST anlegen.
+  # vim /etc/nginx/conf.d/vhosts.conf
+<file http /etc/nginx/conf.d/vhosts.conf>server {
+        listen          80;
+        server_name     mailgraph.nausch.org;
+        access_log      /var/log/nginx/mailgraph_access.log;
+        error_log       /var/log/nginx/mailgraph_errors.log;
+        root /usr/share/mailgraph-ng/;
+        index mailgraph.cgi;
+       location ~ \.php {
+                fastcgi_split_path_info ^(.+\.cgi)(/.+)$;
+                fastcgi_index mailgraph.cgi;
+                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
+                include fastcgi_params;
+        }
+}
+</file>
+Den Parameter **fastcgi_pass** setzen wir im übrigen auf den Wert aus der Konfigurationsdatei //**/etc/php-fpm.d/www.conf**// des PHP FastCGI Process Manager-Daemon **php-fpm**.
+Haben wir die Konfigurationsdatei vervollständigt, prüfen wir diese noch auf syntaktische Fehler.
+   # nginx -t
+   nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
+   nginx: configuration file /etc/nginx/nginx.conf test is successful
+Somit können wir unsere Konfiguration nun noch aktivieren.
+   # systemctl reload nginx
+==== Webaufruf ====
+Rufen wir nun die definierte Webseite unserer Gesamtstatistikübersicht auf, erhalten wir nachfolgende Ansicht.
+{{ :centos:mail_c7:mailgraph-ng_summe.png?direct&800 |Bild: Mailgraph Statistiken (Summe mehrerer Einzelsysteme) }}
+Hier können wir nun gezielt einzelne Systeme auswählen, bzw. bei einer ausgewählten Detailstatistikseite zur Summenseite hin und her wechseln.
 ===== AWStats =====
 Auch mit Hilfe des Projektes/Paketes **AWStats** kann man das Maillog unseres Mailserver auswerten. Mit Hilfe zweier Perlscripte erstellen wir nun täglich einen Statusbericht über das was unserem MX widerfahren ist, und rufen später diese Information via Firefox/Konqueror ab. :)
