[Tutorial] Monitorizare servere & elemente retea ( router, s

[!_30]

Cacti is web-based NMS Open Source software to monitor your network elements ( routers, swtiches,firewall..linux box, solaris box ..etc ).

You require to install Cacti in your Linux box following things are must be installed 1st. - Apache with PHP support - libpng - libzlib - libjpg - net-snmp-devel - mysql Server - mysql client - mysql-devel - openssl-devel - RRDTool must be install on your sytem Graphs

    * Unlimited number of graph items can be defined for each graph optionally utilizing CDEFs or data sources from within cacti.

    * Automatic grouping of GPRINT graph items to AREA, STACK, and LINE[1-3] to allow for quick re-sequencing of graph items.

    * Auto-Padding support to make sure graph legend text lines up.

    * Graph data can be manipulated using the CDEF math functions built into RRDTool. These CDEF functions can be defined in cacti and can be used globally on each graph.

    * Support for all of RRDTool's graph item types including AREA, STACK, LINE[1-3], GPRINT, COMMENT, VRULE, and HRULE

Templates

    * Graph templates enable common graphs to be grouped together by templating. Every field for a normal graph can be templated or specified on a per-graph basis.

    * Data source templates enable common data source types to be grouped together by templating. Every field for a normal data source can be templated or specified on a per-data source basis.

    * Host templates are a group of graph and data source templates that allow you to define common host types. Upon the creation of a host, it will automatically take on the properties of its template.

Graph Display

    * The tree view allows users to create "graph hierarchies" and place graphs on the tree. This is an easy way to manage/organize a large number of graphs.

    * The list view lists the title of each graph in one large list which links the user to the actual graph.

    * The preview view displays all of the graphs in one large list format. This is similar to the default view for the 14all cgi script forRRDTool/MRTG.

User Management

    * User based management allows administrators to create users and assign different levels of permissions to the cacti interface.

    * Permissions can be specified per-graph for each user, making cacti suitable for co location situations.

    * Each user can keep their own graph settings for varying viewing preferences.

The hobbit

Hobbit is a tool for monitoring servers, applications and networks. It collects information about the health of your computers, the applications running on them, and the network connectivity between them. All of this information is presented in a set of simple, intuitive webpages that are updated frequently to reflect changes in the status of your systems.

Hobbit is capable of monitoring a vast set of network services, e.g. mail-servers, web-servers (both plain HTTP and encrypted HTTPS), local server application logs, ressource utilisation and much more.

Much of the information is processed and stored in RRD files, which then form the basis for providing trend graphs showing how e.g. webserver response-times vary over time.

Monitoring network services

conn Simple ping test. Enabled by default, you can disable it by putting "noconn" into bb-hosts.

http Web-server test. Enter the URL to request from the webserver.

ftp FTP server test.

ssh SSH (Secure Shell) server test. Supports ssh1 and ssh2.

telnet Telnet server test.

smtp SMTP (Mail server) test.

pop3 POP-3 test.

imap IMAP test. IMAP version 2 and 4 are supported, for version 3 use "imap3".

nntp NNTP (News) server test.

ldap LDAP (Directory server) test. Enter the full LDAP URI if Hobbit is configured with LDAP support.

rsync rsync server test

bbd Big Brother daemon test. Also works with the Hobbit network daemon.

clamd CLAM anti-virus daemon test.

spamd SpamAssassin anti-spam daemon test.

oratns Oracle TNS listener test. Will attempt to do an oratns "ping".

qmtp QMTP server test. For qmail's qmtpd service.

qmqp QMQP server test. For qmail's qmqpd service.

Hobbit Features

    * Hobbit can handle monitoring lots of systems.

    * Hobbit has a centralized configuration.

    * Hobbit is easy to setup and deploy.

    * Hobbit is actively being developed.

    * Hobbit is licensed as Open Source - Big Brother is not.
