Add button to return back to server Show page on Edit server page

1. Task runs
2. Iterates through all servers and requests to following address for current user count of server:
   • http://<ip_address>/manager/user_count/
3. Response will be current user count of server. If server doesn't respond in 3 retries admin should be notified with message "Unable to reach to retrieve user count upon user limit check".
4. After receiving the current user count of the server, check it with user limit.
5. If it did reach the user limit specified in Server.user_limit, notify admin with message "User limit reached on . User limit: <user_limit>, Current users: <current_user_count>"
6. If it did reach the user limit, it should block the server requesting to following address:
   • http://<ip_address>/manager/add_user_blocked/
7. The server should respond with either TRUE or FALSE.
8. The task checks the response. If it is not blocked ( FALSE) it will retry from step 6.
9. If the retry fails up to 3 times, it should notify admin with message same as on step 3.
10. If step 7 returns TRUE, it should notify admin with message "Server add user is restricted to <user_limit>"

Rewrite all the models and querying in ndb engine

Write a task to migrate all the data to new database engine.

Each server needs to have multiple login information. For example: radius, cisco, snmp.

So what we need here is to add new model called "LoginInfo". See following as sample:

from server.models import Server
class LoginInfo(db.Model):
    url = db.StringProperty()
    username = db.StringProperty()
    password = db.StringProperty()
    server = db.ReferenceProperty(Server)

ReferenceProperty is the field that points to our server. So that we can have multiple login info for each server.

Please allow a user to enter login info on server show page.

Add following fields to models.Server:

• Server.blocked - Boolean
  • Determines if the Server should be blocked by user_limit or expire_date
• Server.token - String
  • Allows the app to talk with other servers defined in models.Server

On edit server page, change cisco ip range to textarea field.

1. Task runs
2. Iterates through all servers and check if any server is expired
3. If server is expired, notifies to admin "Server is expired" and requests to following address:
   • http://<ip_address>/manager/expired/
4. When the request is send to a server it will block itself and respond with the status, TRUE or FALSE.
5. The task checks the response if it is not blocked ( FALSE) it will retry from step 3.
6. If the retry fails up to 3 times it should notify admin with message "Unable to reach to block upon expiry, <expire_date>"
7. If step 4 returns TRUE it should notify admin with message "Server is blocked upon expiry, <expire_date>"

Change navigation in following order:

• Home
• <horizontal bar>
• Server 1
• Server 2
• <horizontal bar>
• Add New Server
• Accounts
• <horizontal bar>
• Logout

Please remove the gray item "SERVERS".

Additionally the sidebar highlight should follow which page the user is on. For example, if user is on account list page, the item in sidebar must be highlighted.

Group server details as following:

• Server name
• Expire date
• User limit
• Radius Config:
  • ip address
  • subnet mask
  • gateway
• Cisco Config:
  • ip address
  • subnet mask
  • gateway
  • ip range
• DNS:
  • DNS1
  • DNS2
• Login details:
  • url1
  • username1
  • password1
  • url2
  • username2
  • password2

Additionally change the flash message design as on twitter bootstrap alert

Add a dashboard page looks like:

You need to know followings:

• Scheduled task to run every 1 minute. It will check all server connections. cron.yaml shows sample implementation.
• Sample cron function will help you to understand how to iterate through the servers.
• Track connection status in a model by pinging each of them. You can fetch_server_url("http://1.1.1.1/", retry_count=3) and check the return value if it has content.

Please include jquery sparkline and use bar chart to display the connection chart.

Add new fields for login info:

• Title
• Protocol

Branch:R12_Title_for_urls
When delete account, server, login info show more detailed confirm box
