# Introduction
SmartMON is a Unix/Linux Infrastructure Monitor, all built on Standard Shell scripts.
Already included powerful monitor functions for Oracle 9i/10g/11g databases and RACs.
The whole system has been tested and smoothly monitored a very large Telecom Product System for several years , which have hundreds hosts and hundreds TB data stored in Oracle Database.
# Deployment
It's very simple to deploy the product when the environment is prepared, only one line code in the crontab:
crontab -e
* * * * * sh /smartmon_agent
## Requirement
### Hardware
One PC Server is OK for monitoring one hundred of machines.
### Software
`OS:` Linux/Unix with FTP service
`Database:` Oracle (9i or above)
### Network
Only two ports of the server should be open to all of the monitored machines:
> `21`, `1521`
## Define the parameters
### Define Services to be monitored
edit file `cmd.cfg`, define available services. Normally you won't need more than the default.
Each service is defined by 2 lines:
# tabdef;;;;;;[=;;;;;
The first line define the table structure and data life cycle in database. The` ` here should equal with `` in the command definition line, that's for the safe check. The `` is exactly the type in Oracle database.
The second line define the execution time cycle, and the process group. `` define the time cycle in seconds, if less than one minute, the actual interval is one minute. That's for the safety concern.
`` define which process should the service use on the monitored machine, if multiple services share the same ``, they will be executed sequently in the same process, otherwise they will be executed separately.
`` define the command/Script to be executed by the service on the monitored machine. For simple command, it can be embedded in the ``. For complex service which need to be done with scripts, the scripts should be stored in `scripts` directory, and in the `` should have a line of command like `sh scripts/some_script_name`
### Define machines to be monitored
edit file `service.cfg`, each line defines a machine and the services on it.
The format is `hostname service1;service2;...;serviceN`
### Define the database
In `db_conn.cfg` file define two database users, they can reside in the same database or separately.
The `alert` database only stores the data no more than 2 hours, so that the alert system can detect events as soon as possible.
The `report` database stores data as much as the definition of services specified by ``, but drop older data. That enable you analyze history events across machines in one pass.
Here is the example
alert sqlplus -s smartmon_alert/smartmon12@"(DESCRIPTION=(ADDRESS=(HOST=10.19.84.10)(PORT=1521)(PROTOCOL=TCP))(CONNECT_DATA=(SID=ols1)))"
report sqlplus -s smartmon_report/smartmon12@"(DESCRIPTION=(ADDRESS=(HOST=10.19.84.10)(PORT=1521)(PROTOCOL=TCP))(CONNECT_DATA=(SID=ols1)))"
You can use external database(s), but you should make sure the monitored machines can access the `1521` port (Oracle Listener port) of the database(s)
### Define the release path
The release path is defined in file `release_server.cfg`. The content contains only one line:
ftp 21
the `` is a directory path which can be accessed by the smartmon OS user via FTP.
It is for every monitored machine to download the latest monitor package, to update their local definitions or scripts in no more than 1 minute when new package is released.
When anyone of the files with suffix `.cfg` or any script file in `scripts` directory is modified, simply execute command `sh release_agent` to distribute the package to all monitored machines.
# Event alert & analyze
This part is not finished yet
## Alert
Override the file `smartmon_alert` to make your own alert system
## Analyze
Currently, use SQL tools to access the `report` database to do analyze manually.
# More
It's open to you to add more functions to the system, such as alert, analyze etc.
