The system is not the end point, but it's the transporter. When the campus dorm WiFi billing system runs, the information office has to deal with it for a long time. Many people think that the transporter is the one who's going to be the one."It's broken."What really is draining attention is the indicators that are not bad but getting worse. Keep a few key points on, the system is going to be stable for several school years; it's only a matter of time before we get rid of the little problems and fail.
First stake: the lifeline of certification success.
For the dormitory WiFi, students sense it."How's the net?"Ninety percent from"Can you get on with it?"So the success rate must be considered as the number one indicator every day. Normality should be at 9:00, and if you go down, you have to check it out without a complaint.——It may be a memory leak from the certification service, it may be that the UA interface is slow or it may be a control in a building. Make the success rate a real-time viewer and drop to threshold automatically alerts, intervene for hours before waiting for a student to call. This line is secured, with complaints being less than half as many as one.
Second-point: accuracy of costing measurement
The most important thing about the system is not miscalculation, but miscalculation until the students blow up the bill. The wiring is regularly checked: whether the actual amount of use and export flow is right or wrong, whether reconciliations are within acceptable range, whether there are duplicate fees or missing accounts. Particular attention is paid to whether the measurement logic has been distorted after system upgrades and rule adjustments. It is recommended that a weekly health report be produced with an abnormal red mark. Once the credibility of measurements is broken, it is extremely difficult to build back.
Third Watch: Loads of Core Equipment and Links
The central platform, building controls, upper access ports, and their load curves are visible. Which equipment hit 90% at the evening peak and which connection started to drop, these are signs of failure. Many schools only look at it when they have a paralyzing condition, and there is no regular surveillance page open.
Fourth Watch: Account number and security incident
The accommodation environment is characterized by a common risk of account sharing, weak passwords, and loosely tied equipment. The transporter is concerned with the wind: the same account is sent in unison, a large number of short-time failures are recorded, an unusual surge in some account flow. These are not necessarily attacks, but they all deserve to be seen. Regular clean-up of zombie accounts, alerting students to poor passwords, and restrictions on unusual sharing, which makes the system safe and clean.
Five-point: the rules in the worksheet and complaints.
Students report and complain, which is the best systematic medical examination."I can't even get it."More. Is it a building or is it a problem?"Deducted fees"Focus, whether the rules are unclear or fail. The pattern is often a system design or communication gap. We suggest that we do a copy of the worksheet once a month, feed high-frequency issues back to the manufacturer or turn them into demand.
You make it routine, not fire.
The transport-based knowledge base and handover determine how well the system will be stable for a few years.
The system runs for years, and the middle-officers change. If all the mistakes are in a teacher's brain, people go out of their way. The daily transport is to settle the knowledge base: every failure, cause, step, order and contact person is kept in one place, clear at the time of the transfer. This is not a thing, but it determines whether the system is running well or running.
We need to keep the alarms in order not to get important things in the noise.
The alarms are too many to be watched. The security guards have to respond immediately to the warning: red is a sign of massive failure, and billing breaks; yellow is a single building with an overload that can be a slow but slow concern; blue is just information records. Different levels go through different channels, red calls directly, yellow entry into the work list pool. After grade, the real vital signals don't get flooded by daily fluctuations. Many schools have no surveillance, and the root is not even heavy, and the feeder is trained for noise."Ignore reflection"。
After all, the quality of the WiFi system for boarding at campus depends on how it is treated."System"Or be treated as."Trouble."The daily watchboard, weekly measurement reports, monthly worksheets are re-recording. These three things form rhythm and the system is always in control. Most feared is that no one will see them, and when they do, they'll be finished and broken. No more input from the carrier is available."Sometimes things happen."Changed"Sometimes you're a little fixer."The information office can sleep safely.
