Symptoms : Server is consuming high levels of CPU capacity – SQL is running slow Impact : Medium Slow SQL responses will degrade the user experience, resulting in poor efficiency. Expected […]
Alert indicates that communications with the internet either gets no response, or only gets a partial response. As well as delays experienced by users, there is the possibility of processes hanging.
A general gauge of user's access to the internet in user functions that depend on external processes via the internet - for example credit card authorization, credit checking, blockchain operation etc.
Jitter reports the degree of variation in latency. Higher levels of jitter are more likely to occur on either slow or heavily congested links - can also lead to data loss and corruption.
Reports a shortage of memory to satisfy all program needs. Steady memory availability level is essential for the server’s good functionality. Lack of system memory can cause high non-cached disk reads and writes.
Paging File Usage indicates the size of the paging file on disk used by the operating system. Alert reports that pressure on available resources (CPU and/or memory) is forcing the system to swap pages from memory to disk, which slows all processes down.
Alert indicates that communications with the SQL server either gets no response, or only gets a partial response. The main effect on performance comes from packet retries which can significantly load the level of network traffic.
Measures the load of all the tasks that are being performed by the server. Business Intelligence applications typically take over 80%; SQL database application usage below 70% is normal. CPU usage above this number means degradation in user response times.
This measure describes the available disk space to store data on the hard disk. Low free storage space can lead to a loss of information and the integrity of the programs and processes in the system.
Reliable connections consistently report back the same latency. AimBetter's alert displays when average internet latency deviates (jitters) longer than the designated time window.
A low latency indicates high network efficiency, high latency means that the network traffic is taking longer times to complete. Network latency has a strong correlation with network jitter.
This measure describes the available disk space to store data in the storage device. Low free storage space can lead to a loss of information and the integrity of the programs and processes in the system.
This alerts means that the hard disk is too busy, therefore cannot apply the input/output operations at the pace that the programs demand. Demand for disk activity may be coming both from the operating system and SQL,
Reports a shortage of memory to satisfy all program needs. Steady memory availability level is essential for the server’s good functionality. The more memory your server has the more cached disk reads and writes it can perform. Lack of system memory can cause high non-cached disk reads and writes.
Measures the load of all the tasks that are being performed by the server. CPU usage below 70% is considered normal. Unusual levels of CPU load activities may be coming from anti-virus scans, backups, restores etc.
Where normal operations are interrupted and data needs to be restored, the further back in time the last backup was done, the more complicated and longer the recovery will be.
Reports when level of usage in percentage of network bandwidth for data transfer from / to server is high. High usage will cause application response times to fall.
