This page provides a sequence of screenshots to help you to |
| 20 |
gain a better understanding of the i-scream distributed |
| 21 |
central monitoring system and how it may be applied in |
| 22 |
networked environments. Click on the thumbnails to |
| 23 |

<b>Reports Centre (Web)</b><br /> |
| 27 |
The i-scream reports centre provides a central access point |
| 28 |
to all web-based reports that are provided by the i-scream |
| 29 |
system. Reports are available to display information |
| 30 |
about the current status of an individual machine and any |
| 31 |
alerts pertaining to either an individual machine, or a |
| 32 |
summary of alerts for all machines. Historical |
| 33 |
information about monitored machines may also be accessed |
| 34 |
from this point. |

<b>Latest Information (Web)</b><br /> |
| 43 |
Here we are viewing the latest information provided by a |
| 44 |
host. Bars are used to represent values such as disk |
| 45 |
space and free memory as this makes it easier to spot casual |
| 46 |
problems. The small graph icons link to historical |
| 47 |
reports of each field for the previous day. The choice |
| 48 |
of fields to display on this page is stored in a separate |
| 49 |
configuration file. |

<b>Conient (Multiplatform real-time client)</b><br /> |
| 58 |
Conient is a real-time client |
| 59 |
that can hook into an i-scream server to allow the user to |
| 60 |
view host information as it passes through the server. |
| 61 |
The client displays information provided by the hosts as well |
| 62 |
as the results of service checks performed by the server on |
| 63 |
each host (eg FTP, Telnet, etc). Conient is written in |
| 64 |
Java and can thus be run on most operating systems. |
| 65 |

<b>Conient (Viewing extra data)</b><br /> |
| 73 |
Less important host information may be viewed in a seperate |
| 74 |
window to avoid clutter in Conient's display. Details |
| 75 |
of the protocol for host-to-server communications are freely |
| 76 |
available to developers. The protocol itself is |
| 77 |
extensible and client programs such as Conient display even |
| 78 |
unrecognised data from modified host programs. |

<b>Conient (Configuration)</b><br /> |
| 87 |
Conient is fully configurable from within the program |
| 88 |
itself. Multiple configurations may be saved. |
| 89 |
Conient can also be configured to connect to a server through |
| 90 |
a firewall via an SSH tunnel or suchlike. |

<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 |
</p> |
| 106 |

<p> |
| 112 |
<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. |
| 120 |

<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. |
| 133 |

<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 |
| 145 |
the "Bersirc" IRC client. |

<p> |
| 153 |
<b>Alerts (Web page)</b><br /> |
| 154 |
Individual alerts and a summary of all alerts raised by the |
| 155 |
i-scream server may be viewed on the alerts web pages. |
| 156 |
These show the different levels of alerts in configurable |
| 157 |
colours and provides specific details about the alerts being |
| 158 |
raised for each machine. |

<b>Alerts (Public helpdesk display)</b><br /> |
| 167 |
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 |
| 171 |
supported web browsers may also automatically scroll the page |
| 172 |
to allow a large font to be employed for easier reading from |
| 173 |
a distance. |

<b>Conient (Server queue monitoring)</b><br /> |
| 182 |
The Conient client may also be used to |
| 183 |
monitor information about the i-scream server itself. |
| 184 |
Here we are viewing the status of the internal queues within |
| 185 |
the server. This shows that the server is performing |
| 186 |
healthily and that there are no bottlenecks. |
| 187 |

<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. |
| 201 |

| 207 |
<p> |
| 208 |
<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 |
| 211 |
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 |
| 216 |
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 ;-) |
