You can use Argus to view the performance indicator, monitoring view, and alarm record of your servers, disks, databases, and other resources in real time. You can also customize the configuration and alarm information of vital resources and control resource usage in real time to ensure stable operation.</p> </section> <section class="section" id="basicfaq__section_ctk_ghp_1kb"><h2 class="doc-tairway">What is an alarm template?</h2> <p class="p">An alarm template contains the alarm rules and contact group information set for a type of monitoring objects. You can configure one or multiple alarm templates for relevant services base on your business demands.</p> </section> <section class="section" id="basicfaq__section_tcb_3hp_1kb"><h2 class="doc-tairway">What is a monitoring item?</h2> <p class="p">A monitoring item refers to a monitoring indicator for collection set by the user or by default, such as CPU usage, memory usage and disk load.</p> </section> <section class="section" id="basicfaq__section_lhx_jhp_1kb"><h2 class="doc-tairway">What is a tag and what is its function?</h2> <p class="p">A tag offers additional information for a monitoring item (metric). For example, df.bytes.used (disk usage) requires two tags:</p> <ul class="ul" id="basicfaq__ul_azp_cgw_4jb"> <li class="li"> mount: Mount point</li> <li class="li"> fstype: File system type</li> </ul> </section> <section class="section" id="basicfaq__section_c3v_mhp_1kb"><h2 class="doc-tairway">What is an alarm rule?</h2> <p class="p">An alarm rule describes an alarm condition. For example, if the CPU usage is over 90% for five consecutive minutes, a P3 alarm will be triggered, three times at most.</p> </section> <section class="section" id="basicfaq__section_zkk_zsh_1kb"><h2 class="doc-tairway">How many alarm levels do we have?</h2> <p class="p">We divide alarms into level P1 to P6 from high to low, a total of six levels.</p> <ul class="ul" id="basicfaq__ul_ytg_dsz_3jb"> <li class="li">P1: Deadly alarms</li> <li class="li">P2: Slightly deadly alarms</li> <li class="li">P3: Severe alarms</li> <li class="li">P4: Serious alarms</li> <li class="li">P5: Alert alarms</li> <li class="li">P6: Caution alarms</li> </ul> </section> <section class="section" id="basicfaq__section_v4w_wgp_1kb"><h2 class="doc-tairway">By what dimensions can the monitoring chart be displayed?</h2> <p class="p">The monitoring chart can be displayed by two dimensions: monitoring items and instances.</p> <ul class="ul" id="basicfaq__ul_qcc_5cw_jkb"> <li class="li"><strong class="ph b">The perspective of metrics</strong>: each graph covers a metric. You can view the metric’s data change trend of multiple instances in the same graph. For example, if an application has deployed multiple ECS instances, you need to monitor their CPU usage rate. You can add a monitor graph from the perspective of metrics, so that the trend of CPU usage rate of multiple ECS instances over time can be seen in the same graph. <img class="image" id="basicfaq__d23e48" src="https://obs-cn-shanghai.yun.pingan.com/pcp-portal/20201507091432-12335c9190c9.png" width="500"></li> <li class="li"><strong class="ph b">The perspective of <strong class="ph b">in</strong>stances</strong>: each graph covers an instance. You can view different metrics’ data change trend of the same instance in the same graph. For example, if you need to monitor the CPU usage rate, memory used percent, disk used percent and other indicators of an ECS instance, you can add a monitor graph from the perspective of an instance, so that you can view these three metrics’ data change trend of the instance in one graph at the same time.<img class="image" id="basicfaq__d23e57" src="https://obs-cn-shanghai.yun.pingan.com/pcp-portal/20201507091432-1749a7819952.png" width="500"></li> </ul></section>
