<b>Conient (Viewing extra data)</b><br /> |
| 73 |

Less important host information may be viewed in a seperate |

window to avoid clutter in Conient's display. Details |

of the protocol for host-to-server communications are freely |

available to developers. The protocol itself is |
| 77 |

extensible and client programs such as Conient display even |

unrecognised data from modified host programs. |

Conient is fully configurable from within the program |

itself. Multiple configurations may be saved. |

Conient can also be configured to connect to a server through |

<b>ihost (Unix/Linux host)</b><br /> |
| 99 |
> |
The ihost is currently the main Unix/Linux/FreeBSD host |
| 100 |
> |
application for i-scream. ihost is centrally configured |
| 101 |
> |
by the server it connects to and periodically sends |
| 102 |
> |
information about the machine on which it is running. |
| 103 |
> |
The ihost is written in Perl, so can be easily altered to |
| 104 |
> |
send extra information to your i-scream server. |
| 105 |

<b>WinHost (Windows host)</b><br /> |
| 113 |
> |
The WinHost is similar in concept to the ihost, however, this |
| 114 |
> |
one runs on Windows NT/2000 servers. Again, the |
| 115 |
> |
configuration is dynamically obtained from the server. |
| 116 |
> |
The WinHost is typically only present in the Windows system |
| 117 |
> |
tray. Double clicking on the system tray icon will |
| 118 |
> |
bring up a small window that allows data to be viewed and to |
| 119 |
> |
force reconfiguration with the server. |

<b>Alerts (Email)</b><br /> |
| 128 |

The i-scream server includes many alerting mechanisms. |
| 129 |
> |
Simple email alerts may be sent out if desired. Alert |
| 130 |
> |
levels and frequencies may be configured for the |
| 131 |

server. This screenshot shows the format of a typical |
| 132 |

alert; the contents of which are of course configurable. |

<b>Alerts (IRC bot)</b><br /> |
| 141 |

Another i-scream alerter comes in the form of an interactive |
| 142 |
> |
IRC bot. This may reside in an IRC (Internet relay |
| 143 |
> |
chat) channel and broadcasts alerts if told to do so. |
| 144 |

This screenshot shows a typical interaction with a user in |

Individual alerts and a summary of all alerts raised by the |

i-scream server may be viewed on the alerts web pages. |
| 156 |

These show the different levels of alerts in configurable |

The reports centre also |
| 168 |

provides a page that may be useful in configuring |
| 169 |

non-interactive public displays of alerts. These |
| 170 |

displays automatically refresh the page periodically and |

monitor information about the i-scream server itself. |

<b>Historical reports (Web)</b><br /> |
| 195 |

Historical information is collated by the |
| 196 |

i-scream server into (typically) a MySQL database. A |
| 197 |
> |
separate program is used to produce the historical web |
| 198 |

reports These may be browsed via this web-based interface |
| 199 |

(see screenshot). The reports to be generated for each |
| 200 |

machine and the size of the page are of course configurable. |

<b>Historical reports (Metadata)</b><br /> |
| 209 |

The historical report generation also |
| 210 |

produces a number of other files that may be useful for third |

party analysis tools. The chart itself is written as a |
| 212 |

GIF image, as well as a small file suitable for including on |
| 213 |

PHP pages that specifies the minimum and maximum values |
| 214 |

during the 24 hour period. A file containing the raw |
| 215 |

plot data is also produced to enable the use of third party |

on-the-fly plotting tools. |

<b>The i-scream server</b><br /> |
| 225 |
> |
The server is distributed and may therefore have multiple |
| 226 |
> |
points of data entry and run on more than one machine. |
| 227 |
> |
This helps to reduce the amount of host traffic over large |
| 228 |
> |
networks and reduces potential bottlenecks. The server |
| 229 |
> |
is written in Java to allow it to run on most operating |
| 230 |
> |
systems. This exciting screenshot shows the i-scream |
| 231 |

server running ;-) |
