Our system supports virtually any type of network connected service.
Our web interface supports the ability to monitor a selected number of
services on a self-serve basis, such as web servers, mail servers, and so on.
In addition, we have the ability to create custom monitoring scripts
that perform more sophisticated activities such as performing multiple
web page transactions as part of a single monitoring request, connecting
to specialized services for issuing requests (such as databases), etc.
|What types of devices can I monitor?|
If your service is available over the network, we can
arrange for a custom script to monitor your service.
Sensors are the systems we use, scattered strategically across North
America and Europe located in carrier class data centers, to monitor your
servers. Each sensor is a dedicated server operated only by us for
SecuritySpace's services and not shared with any other organization.
This allows us to provide a secure, reliable service.
|What are sensors?|
When monitoring your network from a single sensor, an outage may be
the result of an outage on your system, your ISP, an internet
backbone segment, or our ISP. This can result in false positives
where your network might actually be up and stable, but is simply
not reachable from one of our sensors through no fault of yours.
|Why would I use multiple sensors?|
By employing multiple sensors to monitor you network, you get the
benefit of knowing if an outage is affecting multiple locations, making
it much more likely that the problem is either with your network or
your direct upstream ISP.
When monitoring devices, non-responsiveness or inappropriate
responses (e.g. web pages missing required keywords, etc.) will result
in retries. Our monitoring system will usually make 3 attempts
to get a successful response, and only after all 3 attempts fail will
a device be marked in error.
|How do you handle errors?|
An exception to this three attempt rule is the ICMP ping monitor
which will attempt 15 consecutive pings before reporting the device
in error in any given monitoring interval. Note that the High Frequency
Ping monitor is a different type of device monitoring that adheres to the
3 failed attempt rule before reporting a device in error.
When you purchase a Network monitor subscription, you are given sufficient
credits to use the subscription for the period of time in question.
Sometimes, however, after having made a payment, you may find that you
want to adjust how many devices you are monitoring. The credit system will
allow you to make that adjustment, and you will only use up credits based
on the devices you are actually monitoring.
|What are credits?|
For example, if on January 1st you purchased sufficient credits for 2
Standard devices for one year, and a day later decided to upgrade
to the Advanced device configuration, you would not need to pay anything.
Instead, your credit consumption rate would simply consume the credits
more quickly so that in 6 months, you would have used up all the credits
Our pricing model documents the number of credits you may purchase
for any one device under a given configuration. You are free, however,
to configure the devices however you choose, and however many devices
you want. The only things that changes is the rate at which your credits
The number of credits you have available, the rate at which your credits
are consumed, and the amount of time you have left before your subscription
expires is always shown on the Configure/Status page.
The credit consumption rate depends on your device configuration.
A "Standard" device is one being monitored from one sensor, with
monitoring intervals of no more than once every 15 minutes.
Standard device configurations consume credits at a rate of 1 per day.
|How quickly are credits consumed?|
"Advanced" device configurations consists of devices that are monitored
from more than one location (sensor), and/or at a rate of once every 5 to 10
minutes. Advanced configurations consume credits at a
rate of 2 per day.
"Enterprise" device configuration consists of configurations that monitor
your server every 1 or 2 minutes, or use the High Frequency Ping monitor
to monitor your server every second using ICMP echo requests. Enterprise
configurations consume credits at a rate of 5 per day.
We support both email alerts as well as SMS (text message) alerts.
There is no additional charge for alert notifications, regardless of
notification method being used.
|What types of alert notification do you support?|
Alert profiles allow you to define who will receive notification of
an outage (or a resumption of service). Profiles allow you to indicate
multiple email addresses that may receive an alert, and at what time
the alert is sent. For example, a profile might indicate that front line
support is paged when a network outage occurs, that management is paged
if the outage lasts for more than one hour, and that senior management is
paged if the outage lasts for more than 2 hours.
|What are alert profiles?|
There is no charge for us sending you alerts, nor do we charge you anything
for sending alerts to multiple recipients. You may set up your profile to
notify however many addresses you choose, at the times of your choosing.
The "Make Public" check box allows you to specify that graphs
(and the associated reporting page) are viewable by anyone without
requiring a login. This is usually most useful if you wish to create
a custom page containing our uptime graph on your own web site.
By marking the page as public, you will be able to directly imbed the
image by reference into your own web page and our server will serve
up the latest copy of the image whenever requested.
|What is "Make Public"?|
Yes. You may specifiy fields to be submitted as part of any form
|Do you support web forms?|
Yes. We connect as easily to SSL based web servers as we do to regular
|Do you support secure web sites (SSL)?|
Yes. If your web server generates causes a browser to generate
a userid/password entry dialog box as a result of an HTTP access control
list, you can configure the userid and password to be used to access the
page in question.
|Do you support password protected web sites?|
If you are using a CGI based login approach, our custom multi-page
web scripts can be used to generate logins and form submissions.
Custom scripts, depending on their complexity, will require a setup
fee. Contact us for a quote.
